@cboursnell I filtered my input reads into 1million, 2million...5 million to assemble my transcriptom, then I tried to evaluate these 5 transcriptom by transRate, transRate can generate output CSV files, but just didn't give "score", "optimal score", cutoff and weight, showing "NA"... can you point out what is the problem? Actually transRate works with my non-filtered reads ones... I am wondering if these 5 transcriptom were assembly with too less reads and in very poor quality then transRate can not rate them in score.
So I deleted librt.so.1 and TransRate seemed to be running fine. However I noticed the salmon.log was 4.6GB of error messages like this:
[2017-03-16 00:14:21.704] [jointLog] [warning] [Sampler.hpp]: Failed to sample an alignment for this read; this shouldn't happen
currentMass = -nan, r = 0.677047
I'm afraid maybe some will miss this and use erroneous stats
I find my own results suspicious anyway as they are paradoxical to my Detonate RSEM scores.
Still hoping for a solution to the salmon not installed message. Working from Ubuntu 16.04 LTS.
Hello. I'm looking to evaluate my assembly with RNAseq reads. If I have paired end reads from multiple individuals, do I have concatenate the reads into a single --left.fq and --right.fq file, or can I specify multiple --left and --right fastq files separated by a comma? Thanks.
@MGCBrown you can pass in multiple files, like --left file1_left.fq,file2_left.fq --right file1_right.fq,file2_right.fq
the list of files to each argument should be comma separated, no spaces
you can also provide multiple assemblies and/or reference the same way
@countloki thanks for reporting - we'll make a new release soon that will solve the salmon issues

@blahah and @cboursnell have you guys had any luck finding why salmon gives the "numeric overflow" error on some assemblies (issue #7 on the Transfuse github)? I have found it is reproducible running salmon on directly on the bam file.
Stuart Willis
at least one assembly also repeatably gives the following error, also from salmon: "terminate called after throwing an instance of 'std::bad_alloc'"
Rob Patro
@stuartwillis, any idea if that is still true with a newer salmon?
The version in transrate is very old at this point. Lots of improvements and bug fixes since.
@cboursnell @blahah, I'm booked this week, but perhaps we could work on integrating a newer salmon (and fixing other bugs) the following week, since some ppl seem to have recurring issues with 1.0.3
Stuart Willis
@rob-p, good question, I didn't try; I can check that if would justify upgrading transrate to a newer salmon
Rob Patro
Great. If you still see the error, please file a bug report for salmon so I can see if I can repro the issue upstream.
Stuart Willis
Indeed a more recent version of salmon (0.8.2) was successful on a bam/assembly that repeatedly resulted in a "numeric overflow" with 0.4.2.
However, I also found in the same case that deleting the transrate results (bam and all) and starting over circumvented the problem, while remaking the assembly (transabyss, in this case) circumvented this error in another case. Not sure what to make of that
It does speak to the prescience of @cboursnell to make transfuse able to pick up mid-way, though
@rob-p definitely we should do that - I've been swamped for like 10 months, but this week I've finished up a project so I should have free cycles for it
wow we are super out of sync with salmon
@rob-p how close are we to being able to skip SNAP altogether? in-memory streaming alignment -> assignment -> assessment is the dream we talked about a year ago
Rob Patro
We are ~90% of the way done I'd say. I have 2 students working on this (which also includes some algorithmic advances to rapmap).
Their stuff adds the ability to "selectively" align quasi-mappings. Given that, it'll be a few days of work on the salmon end to enable the posterior sampling with the new code.
@rob-p sweet - that will be such a great update
Stuart Willis
if you guys are tweaking the implementation of salmon into transrate, would it be worth it to add a specification for strand specific data? Not sure how salmon's behavior changes w or w/o on stranded data

Hello @blahah,

Referring to other posts regarding an issue with 1.0.3, I am having a similar SNAP error while running transrate. My error code is noted below.

Welcome to SNAP version 1.0dev.96.

mmap failed.
MemMapDataReader: fail to map /pylon2/bi4s8fp/jsdsmail/Transrate/Trim_TS6_T24.left.pe.qc.fq at 0,3765724304
SNAP exited with exit code 1 from line 2283 of file SNAPLib/DataReader.cpp

Any help/advice on this error would be much appreciated. I got the same error when trying to run it on the previous version of transrate as well.


@jdeyar hmm sorry about that, I'm going to try to work through the transrate issues next week (I'm no longer paid to work on it, and have been swamped with other stuff for a while)
@jdeyar hopefully this is one we can get dealt with quickly by just updating SNAP and Salmon and cleaning up a few packaging issues
@blahah thank you for your prompt response. Hopefully it is as easy as an update for SNAP and other linked software. Please comment in this forum whenever it is updated! Much appreciated!

@blahah any updates so for? I am running Transrate v1.0.3. The algorithms for contig/assembly score are so attractive! Eager to try them out in my data! SNAP seems fine, but Salmon gives warning "[jointLog] [warning] [Sampler.hpp]: Failed to sample an alignment for this read; this shouldn't happen

cc @rob-p \o any ideas?
Rob Patro
Yes (cc @blahah), this is a bug that can occur in VB inference that was fixed in a more recent version of Salmon. I fear the only immediate solution here may be to generate the relevant file manually with a more recent Salmon release --- though we should probably upgrade the one included in Transrate soon
btw, the preprint that describes the relevant algorithm for having salmon do alignment internally went up yesterday --- http://biorxiv.org/content/early/2017/05/17/138800
I think that we can do a patch release before that, but this (rather big new feature) could land soon.
so @rob-p if I cut a new transrate with updated salmon it will fix this?
Rob Patro
This should be the case, yes --- however, before you do that, we should really test the new pipeline on one or two data sets first. A lot has been updated, but the module to sample alignments hasn't been touched in a while.
Thanks! @blahah @rob-p If any testing needed from users, I would like to do it.
Hi Transrate community. I'm hoping someone might be able to provide some advice. Similar to @Victaphanta and @sarjopp earlier in the thread I'm having issues installing all dependencies (namely Salmon_v0.4.0) using the "transrate --install-deps=all" command. As suggested further up I've tried both deleting and renaming local/bin/librt.so.1, both of which did not help. Did this issue ever get resolved? Or at the very least is there an existing/ reliable method to get salmon0.4.0 working?
Matt MacManes
can I hope that when TransRate is updated, @cboursnell can update TransFuse as well? Both of these are really important to my workflow, and are unreliable.. Transfuse is still using Salmon 0.4.2, giving me intractable errors

Rob Patro
wow --- that looks like a hard fail. Presumably a segfault, but I can't really assess from this output.
Matt MacManes
ya, and it’s reproducible… and 100% not worth chasing since it’s a version from 9034 years ago..
Rob Patro
l0l --- true. But presumably we could verify that if we run with 0.8.2 (same index and alignments) everything works?
Matt MacManes
Just did that.. can confirm that everything runs perfect in 0.8.2. :)
Rob Patro
great :) --- we'll get that fixed as soon as Richard and I can sync up. I think getting this issue resolved asap is important. The awesome selective-alignment stuff should probably wait until the subsequent release (after it's had sufficient testing within Salmon itself) ;P.
Hi guys! I'm new in Linux and Transcriptome assembly. I downloaded Transrate but I really don't know how to install it. I did a "make" command but nothing happened. So, how can I install and run Transrate? (I know it's a silly question but as I told you, I'm new in Transcriptome Assembly. I hope you understand
