IGB 4.52 release notes.

• Version 4.52
  • The DAS/2 client has been improved for easier simultaneous viewing of data from multiple DAS/2 servers, and to accept data in the GFF format, if the server makes it available.
    
    
  • Fixes have been applied to allow loading of Affymetrix CHP format files from exon array products containing scores for transcript clusters. Affymetrix data formats are described in documents from the Affymetrix Developers Network.
    
    
  • IGB now allows coloring individual transcripts with individual colors in data from BED format files. This requires extra computational overhead, so use with caution. This setting is activated in the same way as described for the UCSC genome browser:
    • Include itemRgb="On" in the track line
    • Set colors in the 9th column in each bed file data line in the format RRR,GGG,BBB, such as "128,0,255".
    
    
    
  • The track-line property graphType can now be used in Wiggle (".wig") format files. It defaults to "bar" but can also be set to "points".
    
    
  • More options are now available in the pop-up "Change" menu for customizing the appearance of annotation tiers.

  • The map range box now additionally accepts input format "chrX:start+width" in addition to the existing "chrX:start-end".
