Visualize/Caching problem?

Reported by simont | January 20th, 2009 @ 12:29 AM

I was exploring the polymorphic marker problem a bit and ran some analyses on the current production snplotyper and on the production.snptloyper.mcw.edu production branch of the latest code. For the same region and strains, the images did not match, some of the strains are missing all their data.

The databases are the same for these two version of the app (I think?) so the problem must lie elsewhere (ie its not that the data is missing from the database), perhaps that the cache is messed up if that data is being cached somewhere on the new production version when its accessed originally?

Attached is a screenshot of the difference.

    • State changed from “new” to “resolved”

    It seems that using the cache to store the results of the database search for the genotypes was causing some issues. Since the DB wasn't the bottleneck of the process, I've removed the two places I was using the Rails.cache. Based on the example given, it now returns the proper result.
