Problem: When I run a gene expression query, I get a Java stack trace error regardless of whether the query or study is new or previously saved or deployed.

*Topic*: caIntegrator Usage

*Release*: caIntegrator 1.2 and above

*Date entered*: 03/30/2012

Solution

This error occurs in Linux when caIntegrator can not access study data, which by default is stored in the system temporary directory (/tmp). Every time the application is restarted, the contents of this /tmp directory are flushed, so when the user attempts to run a query after the restart, the query will not be able to access the study data it needs, regardless of whether the query is new or if it was saved before the restart.
