tophat2 errors

[ahmetz]

now that we have tophat2 out the door, i'm sure we'll have bunch of tophat2 related error messages and solutions - hopefully.

thank you to the team for releasing the new version. i'm very excited for the combination of tophat and tophat-fusion.

now my problem. I've downloaded and installed bowtie2 and tophat2. everything started out just fine until tophat tried to search for junctions via segment mapping. I got an error 5

Error: segment-based junction search failed with err =-5

I'm hoping it's an easy solution and am sure it's something i did wrong. anyone has any ideas?

Thanks!

[NateP]

I've had an error pop about at the same point when I gave it a test run the other day myself.
Was single end mapping.
Went through the left_kept_reads then:
[timestamp] Searching for junctions via segment mapping
[timestamp] Retrieving sequences for splices
[FAILED]
Error: Splice sequence retrieval failed with err =-6

[Jon_Keats]

Have you tried the fusion version with the -bowtie1 option as suggested when you are doing the fusion detection.

[ahmetz]

yeah, and i also removed fusion detection completely but they all end up giving the same error.

[Nicolas]

Same here. Tophat2 hangs forever at the same step "Searching for junctions via segment mapping", with paired-end HiSeq fastq reads (~140M reads), with or without --fusion-search option.
I ran it succesfully on a small subset of the same files (1M reads), so I suspect it has to deal with data size / memory...
Hope for a quick fix!

[plabaj]

I have a simillar problem at the same stage:
[FAILED]
Error: segment-based junction search failed with err =-6
Error: invalid 'B' array subtype (B)!

and TopHat was run with the following parameters:
--bowtie1 --report-secondary-alignments --bowtie-n

There are quite a few different problems reported in this thread - I apologize for them. We are aware of a couple of these problems and we are trying to fix them, though we are encountering some difficulties reproducing some of these errors.
We just updated the packages on the website with a couple of last minute fixes so please re-download the tophat-2.0.0 package of your choice (yes, it's the same version, same file names) from http://tophat.cbcb.umd.edu and try running the new version again on your test data. If tophat 2 still fails at any stage in the process please report the failure at [email protected] - it would also help if you attach a tarball or zip file with the content of the "logs" directory when you post a bug report there.

Thank you,

The updated version fixed the error I posted earlier in the thread. Thank you for the quick work!

[westerman]

Yes, the updated version also solved the problems I was having with crashes and hangs in the 'Joining segment' part of the program. My samples are being mapped to a non-standard organism that has over 80 scaffolds.

[vyellapa]

I did'nt include the fusion flags and it worked ok. Is anybody seeing any significant speedup compared to 1.4.1? I dont.

Tophat 2 also hangs forever in

[DineshCyanam]

Yes... Tophat 2 is taking extremely long (~ 30 hrs)... particularly the Searching for junctions via segment mapping step as NicoBxl above observed. Here is my log.

Previous versions of Tophat for the same data took ~8 hours to run

[turnersd]

I'm also getting an error when using the --transcript-index option, "GFF transcripts file not found or invalid". The file exists, and it appears valid.

[DineshCyanam]

So I was able to reduce my runtime to ~4 hrs from ~30 hrs by using the --no-coverage-search and --no-novel-indels flags.

Not only is the environment variable ignored, but it also doesn't look in the indexes directory in the directory of the bowtie instance.

The only was it works is if I change directories to /home/darstr/bowtie2/indexes/ and run it from there.
