After running tophat 2.04 with fusion-search (bowtie 1), I wanted to convert the accepted_hits.sam (I put --no-convert-bam param on) to a bam file. So I did :

samtools -bS accepted_hits.sam > accepted_hits.bam
[main_samview]truncated file

here's my tophat command :

tophat -r 60 --b2-sensitive --no-convert-bam --splice-mismatches 1 --min-anchor-length 5 --fusion-search --segment-length 20 --bowtie1 --no-coverage-search --fusion-anchor-length 13 --fusion-min-dist 100000 --mate-std-dev 70 --library-type fr-unstranded --output-dir tophat_2_fusion /home/lab/database/bowtie/ref R1.fastq.gz R2.fastq.gz

After checking in the log file reports.samtools_sort.log0

[bam_sort_core] merging from 23 files...

But I have 28 chromosomes ... indeed when checking the report.log :

tophat_reports v2.0.4 (3480M)
[samopen] SAM header is present: 28 sequences.

So in my sam file there is no alignment on 5 chr ... and that's a problem (...)

Other thing in the tophat.log, here are the last lines of the file :

[2012-08-30 09:22:07] Reporting output tracks
Warning: couldn't remove all temporary files in tophat_2_fusion/tmp/
[2012-08-30 11:13:15] Run complete: 1 days 01:56:41 elapsed

Anyone can help me ?

I think the BAM merging is reported by files, not chromosomes (some chromosomes can be mixed in one file to save space).

Did you check if you have enough disk space during the running? Tophat produces a lot of big files, I have similar problems before because during the running my hard disk fills the quota and the files became truncated.

I contact the guy who is in charge of the grid server and indeed the problem is coming from there (file size limit)
