Galaxy import BAM file error

[leontp587]

I installed my own copy of Galaxy on my local computer. It runs very well, I modified the universe_wsgi.ini file to allow for uploading of bam files from the system path.

So, when I tried to add a bam file to the shared library as admin, I get the error below. Anybody know what is going on here? It's a 55GB bam file.

Traceback (most recent call last):

When you import a bam file, Galaxy is trying to call samtools to check the file's content (to "groom" it as it's called in Galaxy)

This part of the error message:

File "/home/leon/galaxy-dist/lib/galaxy/datatypes/binary.py", line 130, in _get_samtools_version
output = subprocess.Popen( [ 'samtools' ], stderr=subprocess.PIPE, stdout=subprocess.PIPE ).communicate()[1]
File "/usr/lib64/python2.6/subprocess.py", line 642, in __init__
errread, errwrite)
File "/usr/lib64/python2.6/subprocess.py", line 1234, in _execute_child
raise child_exception
OSError: [Errno 2] No such file or directory

means that samtools wasn't found, which could be either because you haven't installed it or because it's in a directory that's not in your system PATH.

Think of Galaxy as a framework. It provides user-friendly access to command line tools (like samtools), but you still have to install these tools.

Best,

By the way,
there is an excellent Galaxy-specific forum at https://biostar.usegalaxy.org/ .
