Alex,
Generally cPickle errors when loading summary trees are a result of indexing gone bad.
Here are a couple notes that should save you some work: *your bowtie indices and 2bit files do not need to be rebuilt; they are not generating these errors; *converting your SAM files to BAM may provide a short-term solution; Trackster SAM support is new and not well tested yet.
Finally, there are many Trackster fixes in galaxy-central, and I believe some of them may solve your issues. For SAM datasets, your best bet is to either (a) try visualizing the datasets with -central or (b) wait for the upcoming (planned for next week) -dist update. If you're still getting errors with the new code base, let us know.
Thanks, J.
I'm running the latest galaxy-dist and Trackster appears to be generally working since I added a couple of reference genomes and users were able to visualize their data. I just rebuilt all relevant references for the sacCer3 (dbkey) genome by concatenating the UCSC chromosome fasta files and building both 2bit file and the bowtie index from the resulting fasta file. The reference genome comes up in the Trackster as I can see the sequence. However, adding a track from the bowtie-mapped data freezes at the "building index" stage and selecting a chromosome in Trackster produces an immediate traceback. Logs are below.
Thanks,
Alex
