Just to add to par's response, if there isn't a per-command log, then just run the last command you find in the run log manually and you'll see the (typically vastly more informative) error message.

tophat is a Python script that calls a number of helper programs (Bowtie2 plus a number of TopHat-specific programs). The broken pipe implies a problem communicating with one of the sub-programs, most likely because it died unexpectedly.
You might try looking in folder1/logs for a run.log file that will show all of the sub-commands that tophat runs. There should also be per-sub-command .log files as well that you could look through with the goal of figuring out (1) which command died and (2) whether it left a more specific error message anywhere.

Tophat2 error ! Broken pipe!
Hi all I am running tophat2 on my proton fastq data reads and have this error which I haven't faced before.
Could you tell me what happened?!
(Sorry for trouble every one , the problem has been sorted! because I didn't have enough space......)
My command:
tophat2 -o folder1 -p 12 --library-type fr-firststrand --keep-fasta-order --GTF genes.gtf Bowtie2Index sample1.fastq
The error is:

The complexity of cancer is clearly demonstrated in the diverse ecosystem of the tumor microenvironment (TME). The TME is made up of numerous cell types and its development begins with the changes that happen during oncogenesis. “Genomic mutations, copy number changes, epigenetic alterations, and alternative gene expression occur to varying degrees within the affected tumor cells,” explained Andrea O’Hara, Ph.D., Strategic Technical Specialist at Azenta. “As...-
