Establishing a Web Services session

To use the BioCyc web services, you must establish a session and log in to your BioCyc account by POSTing your email and password to https://websvc.biocyc.org/credentials/login/. The cookies returned from this request must then be passed back to BioCyc for every subsequent web service request.

Example using curl

    # Log in and save cookies to file biocyc_cookies (POST only):
    curl -c biocyc_cookies -d "email=[email]&password=[password]" -X POST https://websvc.biocyc.org/credentials/login/
    # Issue web service request, passing cookie file:
    curl -b biocyc_cookies https://websvc.biocyc.org/[request]

Example using python Requests module 

    s = requests.Session() # create session
    # Post login credentials to session:
    s.post('https://websvc.biocyc.org/credentials/login/', data={'email':'[email]', 'password':'[password]'})
    # Issue web service request:
    r = s.get('https://websvc.biocyc.org/[request]')

Data Retrieval Web Services: Pathway Tools XML

Any pathway, reaction, compound, gene, protein, RNA or transcription-unit object in a BioCyc database can be retrieved in ptools-xml format, an XML format that is based on and closely resembles the underlying Pathway Tools schema. A single object can be requested using its BioCyc identifier, or a query can be issued using either a subset of the Pathway Tools API functions or the BioVelo query language to retrieve multiple objects.

The following documents will be useful in interpreting the ptools-xml format:

The Pathway Tools Schema Guide A guide to the internal Pathway Tools representation, describing classes and their slots (attributes).
Guide to ptools-xml This document describes the ptools-xml format and the differences between ptools-xml and the Pathway Tools Schema, including the mapping of class and slot names from one to the other.
ptools-xml.xsd An XMLSchema document describing the ptools-xml format
ptools.wsdl A WSDL document describing the ptools-xml-based web services.

Pathway Diagram Painted with Omics Data

Pathway pages can be displayed with omics data superimposed on the pathway diagrams. This operation navigates to the web page for the requested pathway. URLs to generate a pathway web page with overlayed omics data are of the form:

https://websvc.biocyc.org/[ORGID]/new-image?type=PATHWAY&object=[PATHWAY]&[PARAMETER]=[VALUE]

where

The table below outlines the possible paramaters that control the mapping of omics data to pathway diagrams, as well as on the cellular overview diagram (see the next section). In addition, the options detailed in the previous table can be used to customize the rendering of the pathway itself.

Users can submit omics data using a POST request (which allows the omics data to be private). For our examples below we make a data file available on a Pathway Tools web server.

Parameters to Customize Pathway and Cellular Overview Omics-Data Visualizations
Parameter Name Possible Values Pathway (P), Table (T) or Cellular Overview (O) Description Default
datafile A filename P, T, O This parameter is REQUIRED for a POST, and should not be used for a GET. Its value should be a filename.
The file should be tab-delimited, the first column (often referred to as Column 0) being the id of the gene/protein/compound/reaction/other to which the data in the remaining columns applies.		 REQUIRED
for POST
no default
url An example file supplied by the Pathway Tools website administrator P, T, O This parameter is REQUIRED for a GET, and should not be used for a POST. Its value should name an example data file supplied by the Pathway Tools website administrator. REQUIRED
for GET
no default
class gene, protein, compound, reaction, 'NIL' P, T, O gene Gene names and/or identifiers
protein Protein names and/or identifiers
compound Compound names and/or identifiers
reaction Reaction identifiers and/or EC numbers
'NIL' Any of the above

The given value declares the type(s) of the ids found in column 0 (the first column) of the data file. 		gene
column1 numbers separated by space or comma AND/OR,
range of numbers (number pair separated by hyphen)		 P, T, O data columns from datafile to be painted on pathway graphic (e.g. &column1=4-7 9 would select data from columns 4, 5, 6, 7, and 9 in each row of the file.) REQUIRED
no default
expressiontype relative, absolute P, T, O relative: the numerical data represents a ratio (relative to some other dataset or to a control) and is therefore centered around either 0 or 1 (see log parameter below).
absolute: the numerical data represents absolute values, e.g. intensities or concentrations, and are all non-negative.		 relative
log on, off P, T, O on: 0-centered data
off: 1-centered data
  • 0-centered scale: implies that the numerical data of your file can contain positive and negative values. The value 0 is considered to be the center of the numerical values provided in your data file.
  • 1-centered scale: implies that any negative or zero values in your data file should be skipped. Moreover, the data is centered around the value 1 using a log scale. For example, the value 0.1 is considered to be at the same distance to 1 as the value 10. So, a logarithm of base 10 is applied to your data before the linear coloring mapping is applied.
 on
color default, specify, rbg, rbg-cutoff, 3-color P, T
  • default : Orange to gray to blue from data
  • specify : Orange to gray to blue with a maximum cutoff (maxcutoff parameter detailed in this table)
  • rbg : Red to green from data
  • rbg-cutoff : Red to green with a maximum cutoff (maxcutoff parameter detailed in this table)
  • 3-color : Three-color display with a threshold
Data values are divided into color bins. You can choose between a color scheme that ranges from orange (most positive values) through gray in the center to blue (most negative values) or from red through blue in the center to green and yellow. For each of these color schemes, two options are available:
  • The color bins range over the entire spectrum, and the cutoff values for the color bins are derived from the data itself. This means that different experiments could be displayed using different color schemes, making it difficult to directly compare them.
  • You may specify a value for the maximum value cutoff (maxcutoff parameter) bin. All displays that use the same maximum value cutoff will use the same color scheme (assuming other settings are the same), and are therefore directly comparable. The maximum cutoff value should be a number, e.g. 2 or 10, etc. All data values greater than the maximum cutoff value will be displayed in the highest bin color.
A final alternative is to use only three color bins, red for data values that exceed some threshold (see parameter below), purple for data values less than the inverse of that threshold, and gray for values in between. The threshold value should be a number, e.g. 2 or 10.		 default
threshold a numeric value P, T Required if 3-color specified. See discussion in 'color' parameter section of this table. no default
maxcutoff a numeric value P, T Required if specify or rbg-cutoff specified. See discussion in 'color' parameter section of this table. no default
omicsPopups on, unspecified P If present, display the omics data in popup windows, usually one popup per reaction or metabolite in the pathway. This is the only way to show data in multiple columns. A single column of data can either be shown in popups or (if unspecified) as color coded buttons on the diagram. unspecified
defaultPopup bar, plot, heat P The style of data display in the omics popups: a bar graph, an x-y plot, or a heat map. bar

A single column of gene data from the file displayed with colored "buttons":

A single column of gene data from the file displayed with popups:

Five columns of compound (metabolomics) data from the file displayed with popups and heat map as default popup style:

Table of Pathway Diagrams Painted with Omics Data

This operation navigates to a web page containing a table of low-detail pathway diagrams, colored to show omics data values. To submit data via the HTTP GET method, use the following URL format:

https://websvc.biocyc.org/[ORGID]/overview-expression-map?pathways=[PATHWAYS]&[PARAMETER]=[VALUE]

where

The list of available parameters are those marked T in the above Omics Data Parameters Table. The pathway diagrams cannot be customized, and any pathway customization parameters will be ignored. This view is more useful for gene expression data than for metabolomics data, as any side metabolites will not be visible on the pathway diagrams. Popups are also not available with this view -- if multiple data columns are specified, the resulting table will contain a column of pathway diagrams for each data column. The same URL and parameters are used for GET and POST queries except that GET queries must supply the url parameter and POST queries must supply the datafile parameter to upload data from a local file.

Cellular Overview Visualization Services

The following two services navigate to a web page containing the cellular overview (metabolic map) diagram with specified data overlays. For the highlighting service the objects to be highlighted are specified in the URL itself, and highlighting colors are optionally provided. For the omics painting service the objects to be highlighted are specified in a POST, and data overlays are derived from omics data values that are mapped to a color scale.

Highlight/Paint Objects on Metabolic Network Diagram

Objects can be specified for highlighting by name, ID or substring. URLs to highlight specified objects are of the form:

https://websvc.biocyc.org/overviewsWeb/celOv.shtml?orgid=[ORGID]&zoomlevel=[0-3]&[OP]=[VALUES]

where

Multiple highlighting operations can be specified in a single URL. The possible highlighting operations are described in the following table. Note that all these operations correspond to the operations available from the top menu bar when a Cellular Overview diagram is displayed. The operation xnids is special as it accepts data values as well. A data value can be specified after each name.
Op Highlight Operation
rnids Highlight reaction names or frame ids.
rsubs Highlight reaction substrings.
recns Highlight reaction EC numbers.
pnids Highlight pathway names or frame ids.
psubs Highlight pathway substrings.
gnids Highlight gene names or frame ids.
gsubs Highlight gene substrings.
enids Highlight enzyme names or frame ids.
esubs Highlight enzyme substrings.
cnids Highlight compound names or frame ids.
csubs Highlight compound substrings.
xnids Highlight a mix of names and frame ids with or without omics data.
pcids Highlight pathways based on curation status.
rcids Highlight reactions based on curation status.
revis Highlight reactions based on evidence selected.
pevis Highlight pathways based on evidence selected.
gregs Highlight genes based on regulation selected.
greps Highlight genes based on replicons.

The string specified after the ‘=’ for an operation must not be quoted, and any special characters must be URL encoded. The string is not case-sensitive. Multiple values separated by commas may be supplied for any of the above operations (except xnids, which uses URL-encoded spaces as separators). There is no difference between suppling multiple comma-separated values for a single operation versus specifying that operation multiple times, once for each value. When supplying omics data values using the xnids operation, the id and the value should be separated by a URL-encoded space. If multiple objects are specified using the xnids operation, either all must have data values (resulting in an omics viewer display), or any data values will be ignored (reverting to a basic highlighting operation).

Example highlighting URLs are as follows.

Paint Omics Data from a File on Metabolic Network Diagram

The metabolic network diagram can be invoked by using a URL link that specifies an omics data file that resides on an accessible website. See the Omics Viewer section of the Website Users Guide for more information about the Omics Viewer, including the data file format. This GET request will navigate to the Cellular Omics Viewer page and load it with data from the supplied URL and the parameters specified in the request itself.

URLs to paint omics data on the cellular overview diagram are of the form:

https://websvc.biocyc.org/overviewsWeb/celOv.shtml?orgid=[ORGID]&omics=t&zoomlevel=[0-3]&[PARAMETER]=[VALUE]

where

The list of available parameters are those marked O in the Omics Data Parameters Table.

SmartTables

SmartTable Data Retrieval

SmartTable data can be accessed from a web service in the following formats: JSON, XML, or tab delimited. This web service will request your account username and password.

The basic URL to retrieve a SmartTable is:

https://websvc.biocyc.org/st-get?id=[SMARTTABLE-ID]&format=[json|xml|tsv]

where

An example of the JSON structure can be found in the JSON Structure for SmartTables Retrieval and Creation.

Example URL:

SmartTable Creation

To create a SmartTable from data supplied via a file using the web service URL, the user must use a tool that can peform a "PUT" method. The result returned will contain the identifier of the created SmartTable. curl will be used for examples in this documentation section. When using curl, the terminal command may look like the following:

curl -u '[USER@DOMAIN.COM]' -X PUT -T [ST-PATH] https://websvc.biocyc.org/st-create?format=[json|xml|tsv]&orgid=[ORGID]&class=[CLASS]

where

Example terminal command:

For tsv (tab-separated-values) input files, the orgid and type args are required; for json and xml input files, those parameters are encoded as part of the file format. For tsv input files, the first row of the file is assumed to contain column headers.

JSON Structure for SmartTable Data Retrieval and Creation

JSON file structure:

JSON examples: 

// Short form
{"name": "sample short-form group",
 "description": "sample short-form description",
 "pgdb": "ECOLI",
 "type": "Genes",
 "values": ["trpA", "trpB"]
}

// long form (2 columns)
{"name": "sample long-form group",
 "description": "This is a longer form of JSON used with a SmartTable.",
 "columns": [{"name": "Gene",
                      "type": "Genes"},
                    {"name": "Expression Level"}]
 "rows": [{{"frameid": "EG11204", "pgdb": "ECOLI"},
                 "1.3"}
      {{"frameid": "EG11205", "pgdb": "ECOLI"},
        "-2.2"}]
}
