GSoC 2016 – Week 12

This week I worked on improving the notifications framework based on my mentors’s comments. The notifications framework is pretty much done; https://github.com/Murali-group/GraphSpace/pull/191 . This week I’ll try to implement share graph layouts notifications also as a part of this framework.

This week I need submit code and my evaluations so I will review the GPML uploader once again.

It was a great summer 🙂

Thanks @tmmurali@adbharadwaj for all the help 🙂

GSoC 2016 – Week 11

Now we have a working version for share graph events notifications.

The basic layout of the notifications page when the user is logged in.

The page is ‘AJAX ed’ by using the window.location.reload() method, so the user doesn’t need to refresh the page after clicking on Mark as read on the page. We took inspiration from GitHub notifications for GraphSpace notifications. Once the user marks a notification as read it disappears from the notifications page, but a user can look at all the notifications, read and unread, of a group by clicking at the group link in the left column.  More screen shots are uploaded on the notifications framework PR on github. https://github.com/Murali-group/GraphSpace/pull/191 . This week we will work on the review of this PR and get all the documentation and user guide in for GPML uploader as well as Notifications.

Summer flew by really fast 🙂

Cheers!

GSoC 2016 – Week 10

This week we worked on a prototype of the notifications framework. We are working on finalising the API for the framework and also getting it throughly tested. Right now users can get their notifications after logging in at graphspace.org/notifications (this is not pushed on the website yet) and mark them as read, but this is not ‘AJAX ed’ right now i.e. users need to refresh the page to fetch the updated notifications again. This should be done in the following week.

The GPML uploader script part is now done 🙂 The verdict is:

Out of 2492 pathways present on WikiPathways, 1258 didn’t pass our GPML uploader. Two reasons:

  • GraphRefs not available for source and target nodes – 1100
  • Shape element type not supported by GraphSpace – 158

 

NOTE :  [‘mim-degradation’, ‘mim-phosphorylated’, ‘sarcoplasmic reticulum’, ‘mitochondria’, ‘endoplasmic reticulum’, ‘golgi apparatus’, ‘mim-interaction’] are not supported by GraphSpace as they can’t be drawn using cytoscape.js

GSoC 2016 – Week 9

This week involved two tasks; first one was to implement some boiler plate code for the notifications framework and the second one was to test the GPML uploader thoroughly.

As discussed with my mentors during my weekly meetings I have started working on the notifications framework https://github.com/Murali-group/GraphSpace/pull/191 . The users of a group will be notified whenever a graph is shared in a group they are a part of. A initial rough design for it:

Moving on the GPML uploader testing part. I got stuck while installing a new instance of GraphSpace, the current procedure as detailed in README is faulty and Ted is working on fixing it right now. He also helped me to get the instance working as it was desperately needed to run the upload script. Thanks Ted 🙂 As we are using SQLite as our database my script is overloading the database and hence it wasn’t able to handle all the requests sent through the script (1999 out of ~2700 were processed). I have now added a time delay to every CURL request. We guess this should work. I’ll upload a detailed analysis of the results once we go through it.

Summer going really fast!! Looking forward to getting a nice version of the notifications framework merged before the end of official coding period 🙂

Cheers!

 

 

 

 

GSoC 2016 – Week 8

After working through the testing script we discussed the failures with Alexander Pico. I am still working on the review of the uploader and the script. While working on this I tried to create a new instance copy of GraphSpace and I got stuck at an issue. (https://github.com/Murali-group/GraphSpace/issues/186) I am working on finding the root of this problem, I suppose it is not related to the GraphSpace codebase.

After discussion with my mentors last week we decided to work on the notification framework for GraphSpace. We started working on a basic model which will alert users of a group if a new graph is shared within the group. For this my mentors helped me to design a new database table. Hoping to get a working notification framework by the end of the summer 🙂

GSoC 2016 – Week 7

This week we decided to work on testing the GPML uploader feature of GraphSpace.

For this we downloaded all the pathways from the WikiPathways website and uploaded them to GraphSpace using the REST API. The script to do this can be found here. https://gist.github.com/MridulS/2a406ed5c2a465531b5e924af41e3eca

The preliminary results suggest that a total of 970 pathways were able to pass the API call out of 2857. The ones which weren’t able to pass had properties like ‘mitochondria’ for shape and some interactions missed the GraphId, which should be present according to the schema (that’s why the assumption that GraphId is required for all interactions) The uploader will be updated to throw an error in these cases.

Out of the 970 that passed the API call 518 were successfully uploaded on the GraphSpace website and and 452 failed the tests for presence of GraphRefs for interaction. The output can be seen here. https://gist.github.com/MridulS/bbdf0de7b6cec55d00e509e688f40075 it is a dictionary with the API return message keyed by the Pathway ID.

The uploader will be improved further on the results of this test.

This activity helped us discover things like different shapes that wasn’t possible to catch manually.

 

GSoC 2015 – Week 6

This week was broadly used to address the comments of my mentors and improving the code. The first major comment was regarding using source and targets while drawing edges. We were using dummy nodes to show edges, by using the start and end coordinates of the given interactions. Now GPML uploader uses the GraphRef attribute to find the source and target nodes. Again there are some problems with this approach as there are files like http://www.wikipathways.org/index.php/Pathway:WP109 which don’t specify the GraphRef for source and target nodes. Currently we are thinking of throwing an error if GraphRefs aren’t present. To test this further I am writing to script to scrape through the wikipathways file and test the GPML uploader for all the files listed there, using http://webservice.wikipathways.org/listPathways and the API http://webservice.wikipathways.org/getPathwayAs?fileType=gpml&pwId=WP4&revision=0 and count the errors we encounter with our GPML uploader.

To use the graphspace interface I did a pretty naive thing, copying the file itself to the folder (dumb I know). I did this beacause the normal way of importing wasn’t working for some reason. To debug this I started looking for namespace collisions, couldn’t find any (technically good for the code, bad for me :/). The solution turns out to be pretty simple, delete the .pyc files because they are still present after you delete the original files and my import was importing the old .pyc file hence wasn’t able to debug.

More to come, thinking of blogging twice a week!

Cheers!
