In my case I forgot the -C for colorspace reads. Since bowtie won't run in this case, it will give the same error message. This behavior of tophat really needs to be corrected and the output of bowtie has to be shown on screen.

For anyone else who runs into this problem: Get the file logs/run.log from your tophat output directory. Search for the line that starts with bowtie and copy/paste it into a command line. Bowtie will fail and the error message tells you what the problem was.Comment

Here is a patch for tophat 1.2.0 that fixes this:
< if not os.path.isfile(unmapped_reads_fasta_name):
< sys.stderr.write("Error: Bowtie results not found, error message from bowtie was:\n")
< logData = open(logging_dir + tmp_fname + ".log").read()
< sys.stderr.write(logData)
< sys.exit(1)

Thank you for your post. I fix the problem. I realised that I was using the whole genome itself instead the reads..

NGS has revolutionized clinical microbiology by offering new ways to identify and surveil pathogens without prior knowledge of the target. One popular approach is 16S rRNA and ITS amplicon sequencing, which targets specific microbial markers. But studies are increasingly incorporating shotgun metagenomics, a technique that sequences all DNA from a sample without targeting specific microbial markers. This approach allows more detailed taxonomic classification, detection...Yesterday, 06:46 AM -
Tumors contain complex mixtures of cell populations that evolve in response to treatment and host-specific factors. Tissue biopsies provide only static snapshots of a tumor’s state. But what if we could follow that evolution over time using a minimally invasive technique?
Liquid biopsies can detect tumor-derived material circulating in the bloodstream, providing a way to study treatment response, detect emerging resistance, and discover new biomarkers. Circulating...10-14-2026, 09:55 AM
