2. About the project
2
The Objectives of the project is to :
• Develop a Stoichiometry Plugin for Pathvisio.
• Improving validation through the PathVisio-
Validator plug-in.
• To Provide SBGN validation in the Validator -Plugin
and to update SBGN Plugin – to deal with ‘Auxiliary
Units’ issues.

3. Stoichiometry Plugin
3
The Plugin is aimed at producing a
Stoichiometry Matrix for a standard biological
Process Diagram(i.e the causal sequences of
molecular processes and their results).

4. Features:
4
• Generate a Stoichiometric Matrix for Process
Diagram .
• Can generate an “.txt” file containing Stoichiometry
Matrix .

11. Improving validation through the PathVisio-
Validator Plug-in
11
Created some new validation rules in
schematron to check valdations like:
• a logic arc should always connect to a logic gate, such as "OR" or
"AND“
• process nodes should have at least one input and at least one
ouput pointing to the arcs
• Whether a certain Glyph is allowed in PD,ER,AF languages

Created some of the pass/fail test-cases
for Process Diagram, Activity Flow, Entity Relation
Languages.

13. To Provide SBGN validation in the Validator Plugin.
13
Earlier the Validator plugin was able to validate on
MIMML and GPML format, Hence I have enhanced the
functionality and provided the validation for SBGN format
too.
• Now theValidator Plugin automatically selects the ruleset
based on the format. Possible formats: GPML, MIMML,
SBGN-PD,ER,AF

14. Feature:
14
• we can simply choose to validate it, the plugin can
understand which format it is and validates
accordingly based on the format.
(or)
• We can explicitly validate the pathway against any of
the Ruleset (choosing Ruleset manually).
