Dear all, I updated to the latest Galaxy stable code, and updated the datatypes_conf.xml. Trackster displays an error after opening a saved view: *********************** Error: The requested genome file (/home/galaxy/galaxy-dist/tool-data/shared/ucsc/chrom/dm3.len) could not be opened. Exiting! sort: write failed: standard output: Broken pipe sort: write error Couldn't open /home/galaxy/galaxy-dist/tool-data/shared/ucsc/chrom/dm3.len , No such file or directory *********************** In my universe_wsgi.ini I point to the correct directory where I keep my chrom len files. # Directory where chrom len files are kept, currently mainly used by trackster len_file_path = /mnt/referencedata/trackster Thanks for any advice, Cheers, Joachim -- Joachim Jacob Contact details: http://www.bits.vib.be/index.php/about/80-team
