I am attempting to run cuffdiff and have used this tool successfully in the past. For some reason I am seeing unusual behavior in this tool. I have 6 groups with 3 replicates each. When I attempt to add the replicates to each group the drop down menu is populated with all of my accepted hits.bam files from Tophat for all samples. However, when I change the input to allow multiple datasets so that I can load the 3 replicates per group the drop down menu now only allows me to select a subset of all the bam files from Tophat. The scroll bar on the side of each drop down also is not working. I tried re-starting Galaxy and I also tried building a workflow for this but I am still seeing the same behavior. Any help is appreciated.
