Hi all, We have recently updated our local Galaxy installation to vrelease_2014.02.10--2--29ce93a13ac7 (database version is 118). I found that the Trackster is not working. I have checked the latest commits related to Trackster bugs. So i have updated theses files: ./static/scripts/viz/trackster.js (commits date: 2014-02-28) ./static/scripts/viz/trackster_ui.js (commits date: 2014-02-28) ./static/scripts/viz/trackster/tracks.js (commits date: 2014-03-16) ./static/scripts/utils/utils.js (commits date: 2014-03-19) ./static/scripts/utils/config.js (commits date: 2014-03-15) But, it is still not working. I have tried different format…bam, bed, sam….all are not working. I looked into all possible files I can think about that might cause the problems but still don't have any clues. I also looked into the log, and there is no error, but i noticed that there is difference from the log where the trackster was working in previous installation. The log where the trackster is not working: 1. "GET /galaxy-dev/visualization/trackster?dataset_id=f04ecb1d3d259245&hda_ldda=hda The log where the trackster is working (from the old installation): 1. "GET /galaxy/visualization/trackster?dataset_id=5d38b380cba2f4a6&hda_ldda=hda…… 2. "GET /galaxy/api/datasets/5d38b380cba2f4a6?hda_ldda=hda&data_type=converted_datasets_state…. 3. "GET /galaxy/api/datasets/5d38b380cba2f4a6?data_type=data&chrom=chr2L….. It looks like that the trackster in new version of Galaxy does not execute the second and the third steps. Here is the screen shot when i clicked "View in new visualization" (there is nothing shown up---blank) Any ideas or suggestions are appreciated. Thank you very much. Best, Shu-Yi
