I recently installed Galaxy on Ubuntu 12.04.1 LTS. Bowtie, SAMtools, and Tophat all run fine with my small subset of paired-end Illumina reads. Unfortunately, it seems to only partially work when I run Cufflinks v2.0.2. Three entires in my history appear (gene expression, transcript expression, and assembled transcripts) containing reasonable output. Each of these entries is highlighted red, though without the red circle with an X. The box contains the message: An error occurred running this job: cufflinks v2.0.2 cufflinks -q --no-update-check -l 300000 -F 0.100000 -j 0.150000 -p 4 cp: cannot stat ` /home/galaxy/galaxy-dist/database/job_working_directory/000/20/global_model.txt': No such file or directory What is this global_model.txt file and why might it be missing/have failed?
