Hi, I am trying to set up the visualization functionality on our local Galaxy installation. I followed the instructions on https://wiki.galaxyproject.org/Visualization%20Setup And here is the list of len files: ls -l tool-data/shared/ucsc/chrom/ total 200 -rw-rw-r-- 1 galaxy galaxy 10 Jan 27 15:13 centromeres1.len -rw-rw-r-- 1 galaxy galaxy 821 Jan 27 15:13 hg15.len -rw-rw-r-- 1 galaxy galaxy 713 Jan 27 15:13 hg16.len -rw-rw-r-- 1 galaxy galaxy 792 Jan 27 15:13 hg17.len -rw-rw-r-- 1 galaxy galaxy 855 Jan 27 15:13 hg18.len -rw-rw-r-- 1 galaxy galaxy 202 Jan 27 15:13 hg19Haps.len -rwxr-xr-x 1 galaxy galaxy 1971 Jan 27 15:13 hg19.len -rw-rw-r-- 1 galaxy galaxy 67 Jan 27 15:13 hg19LggInv.len -rw-rw-r-- 1 galaxy galaxy 4516 Jan 27 15:13 hg19Patch10.len -rw-rw-r-- 1 galaxy galaxy 1983 Jan 27 15:13 hg19Patch2.len -rw-rw-r-- 1 galaxy galaxy 2844 Jan 27 15:13 hg19Patch5.len -rw-rw-r-- 1 galaxy galaxy 3879 Jan 27 15:13 hg19Patch9.len -rw-rw-r-- 1 galaxy galaxy 11672 Jan 27 15:13 hg38.len -rw-rw-r-- 1 galaxy galaxy 67 Jan 27 15:13 hlaRef1.len -rw-rw-r-- 1 galaxy galaxy 67 Jan 27 15:13 hlaRef2.len -rw-rw-r-- 1 galaxy galaxy 67 Jan 27 15:13 hlaRef3.len -rw-rw-r-- 1 galaxy galaxy 67 Jan 27 15:13 repBase0.len -rw-rw-r-- 1 galaxy galaxy 67 Jan 27 15:13 repBase1.len -rw-rw-r-- 1 galaxy galaxy 12697 Jan 27 15:13 repeats2.len -rw-rw-r-- 1 galaxy galaxy 67 Jan 27 15:13 simHuman.len -rw-rw-r-- 1 galaxy galaxy 67 Jan 27 15:13 simHumanMammal.len -rw-rw-r-- 1 galaxy galaxy 362 Jan 27 15:13 venter1.len When I test the visualization through Trackster. I got the following error after seeing a message saying "preparing the data, this can take a while": Error: The requested genome file (tool- data/shared/ucsc/chrom/hg18.len) could not be opened. Exiting! sort: write failed: standard output: Broken pipe sort: write error Couldn't open tool-data/shared/ucsc/chrom/hg18.len , No such file or directory. It seems something else failed in the middle of visualization as I do have the hg18.len under the default path with the global reading permission.. Does anybody have similar experience? Is there is way for me to debug? Best, Yupu

Hi Yupu Just double checking: Have you restarted your Galaxy server after adding the len files? Regards, Hans-Rudolf

Yes I have restarted my Galaxy many times and I have also tried different genome build such as hg18 and experience the same problem. Yupu

Hello Yupu, Using a .len file is problematic at this time. In the upcoming release this will be corrected. Using a .fasta file is the solution. In many cases, using a .fasta file can be preferred as it will include the reference genome sequence in the visualization, but the choice is yours, once the correction is released to the distribution. More about this is in a recent post from Jeremy: http://lists.bx.psu.edu/pipermail/galaxy-user/2014-January/007106.html Our apologies for the confusion this caused. The advice from Hans- Rudolf is under normal circumstances the best first-pass route for troubleshooting, and you will want to restart after using the fasta method as well.

Hi Yupu, I'm sorry, I mixed up the processing for custom builds with the processing for installed builds in my initial reply. A .2bit & .len file are appropriate for what you are doing - and the wiki instructions are accurate. Still, I double checked with Jeremy, the scientist that developed the tool, about your issue. He found that the full path to the .len file needs to be specified right now in order for installed builds to function correctly. This deviates from the wiki instructions, but we consider this a bug and plan to correct it in the next release. Please try using the full path and let us know how that works out, Jen Galaxy team -- Jennifer Hillman-Jackson http://galaxyproject.org

Using full path in the ini file fix the problem! Thanks, Yupu

Yupu, Very glad! The thanks goes to Jeremy who sorted out the issue. We had some big changes the last few release cycles, and unexpected issues popped out. It was very nice of you to not only take the time to report the problem, but to also follow up with sending feedback until resolved. If this is not corrected soon for some reason (as it is expected to be), I will add a temporary note to the wiki instructions. But, mainling list Q & A, like this conversation, will show up in our Galaxy custom searches. So can certainly help others, just as it is, right now. Thanks again, your patience and help confirming the work-around in a local build (one not run by a team member) are very much appreciated!
