Hi I have noticed a few bugs while using trackster: 1. Multiple versions of visualisation saved. Quite often if I am working on a visualisation I save periodically after adding tracks or bookmarks or display options. When I go back to my visualisation menu there are now several different versions of the same visualisation. This doesn't always happen and I haven't figured out a direct cause yet. 2. While viewing bookmarked regions in my visualisation the whole Galaxy process crashed and needed to be restarted. I found the error below in paster.log. Other than that Trackster has been a very valuable tool. Thanks Shaun Webb Error - <type 'exceptions.IOError'>: [Errno 24] Too many open files: '/storage/home/galaxy/galaxy_dist/database/files/068/dataset_68559.dat' URL: http://bifx-core.bio.ed.ac.uk:8080/tracks/converted_datasets_state?hda_ldda=hda&dataset_id=608cc0a44f2421fa&chrom=chrIX File '/storage/home/galaxy/galaxy_dist/eggs/Paste-1.6-py2.6.egg/paste/exceptions/errormiddleware.py', line 143 in __call__ app_iter = self.application(environ, start_response) File '/storage/home/galaxy/galaxy_dist/eggs/Paste-1.6-py2.6.egg/paste/recursive.py', line 80 in __call__ return self.application(environ, start_response) File '/storage/home/galaxy/galaxy_dist/eggs/Paste-1.6-py2.6.egg/paste/httpexceptions.py', line 632 in __call__ return self.application(environ, start_response) File '/storage/home/galaxy/galaxy_dist/lib/galaxy/web/framework/base.py', line 160 in __call__ body = method( trans, **kwargs ) File '/storage/home/galaxy/galaxy_dist/lib/galaxy/web/framework/__init__.py', line 67 in decorator return simplejson.dumps( func( self, trans, *args, **kwargs ) ) File '/storage/home/galaxy/galaxy_dist/lib/galaxy/web/controllers/tracks.py', line 549 in converted_datasets_state if not standalone_provider.has_data( chrom ): File '/storage/home/galaxy/galaxy_dist/lib/galaxy/visualization/tracks/data_providers.py', line 738 in has_data f, bbi = self._get_dataset() File '/storage/home/galaxy/galaxy_dist/lib/galaxy/visualization/tracks/data_providers.py', line 827 in _get_dataset f = open( self.converted_dataset.file_name ) IOError: [Errno 24] Too many open files: '/storage/home/galaxy/galaxy_dist/database/files/068/dataset_68559.dat' -- The University of Edinburgh is a charitable body, registered in Scotland, with registration number SC005336.
