Transrate for metatranscriptome data

[chc*]

Hi all,

I am trying to install and use Transrate to assess the quality of different assemblies of some metatranscriptome data I have. However when I use gem install and then try to install dependencies this is what I get:
$ sudo /users/bmg/chc/bin/transrate --install-deps read
[sudo] password for chc:
Checking dependencies
Installing snap (1.0beta.18)...
Installing bam-read (1.0.0)...
Installing salmon (0.4)...
[ERROR] 2016-03-31 12:31:38 : Failed to install:
- salmon:0.4

Does anyone have any ideas how to work around this non- informative error??

Not a direct answer for your question.

If you are referring to salmon (counting program) then 0.4 is an old version. Perhaps you could manually install salmon binaries from here: https://github.com/COMBINE-lab/salmon/releases If transrate requires that particular version then you could try installing that manually.

Hi chc, transrate author here.

For some reason, transrate has tried to install the salmon dependency but can't find it afterwards. It might be related to using sudo - you shouldn't have to use sudo with transrate and doing so is likely to cause problems (because sudo often leads to a different user space being visible to the programs it runs).

The easiest way to install transrate, and the recommended option unless you want to use it as a dependency in a Ruby program, is to use the pre-packaged install.

You can grab 1.0.1 here: https://github.com/Blahah/transrate/releases/tag/v1.0.1

I'll be releasing a new version ASAP, hopefully today, with the latest Salmon release, but 1.0.1 should work fine.
