I checked the version of bx-python egg and confirmed that it is bx_python-0.7.1_7b95ff194725-py2.7-linux-x86_64-ucs2.egg.

I will upload the dataset to the public server and try it over there and report.


Thanks,

Would it be possible that you have an old copy of the bx-python egg?
You should have bx-python 0.7.1

If you check your eggs directory and you see version 0.7.1, then there
may be something wrong with bx-python. In this case, please upload
your build and bam to our public server and try again; if it fails on
our public server, share the datasets with me and I'll take a look.

Thanks,
J.

Hello,

I am trying to visualize a large genome (Large number of scaffolds)
and a large (bam file) in trackster on our local galaxy instance
(running release_2014.02.10).
When ever I try to do the above I see the following error in the logs:

  File "bbi_file.pyx", line 215, in bx.bbi.bbi_file.BBIFile.query
(lib/bx/bbi/bbi_file.c:5596)

AttributeError: 'BinaryFileReader' object has no attribute 'read_bits64'

Trackster works OK when I load smaller data sets.

It seems that there was a fix for this in bx-python code, as per mail
from Jeremy
(http://dev.list.galaxyproject.org/trackster-error-for-viewing-rat-data-rn5-tp4662664p4662672.html).
How do I get the fixed code into my galaxy instance?

Thanks,
