galaxy-dist commit 11031e92204b: trackster: Add proper CIGAR support to BAM display (properly displays matches, deletions, skipped bases, and clipping. Padding and insertions are skipped as of now as there is no good way to insert new space into the view.)
# HG changeset patch -- Bitbucket.org # Project galaxy-dist # URL http://bitbucket.org/galaxy/galaxy-dist/overview # User Kanwei Li <kanwei@gmail.com> # Date 1287529137 14400 # Node ID 11031e92204b1590ff05119515673d37ae834188 # Parent ad9bb65d2d153af5db0ae497930eb35d17f63057 trackster: Add proper CIGAR support to BAM display (properly displays matches, deletions, skipped bases, and clipping. Padding and insertions are skipped as of now as there is no good way to insert new space into the view.) - Don't re-add new datasets when refreshing after using "Add into current viz" link - To prevent browser lockup, only display up to 50 lines of features by default (user-editable in future).
