Version 1.12.1.1.358 release 8 November 2005

New Features

  1. Multi region reading (MRR). A single sequence may encompass a larger region including more than one exon. In most cases the user will get more data with less sequencing reactions. The MRR feature is extremely useful, in particular when a larger amplicon is used as a sequencing template.
  2. The ability to toggling on or off a particular sequence during analysis. The color of the corresponding arrow will change from yellow into blue. This feature allows better understanding of the effect of a particular sequence on allele assignment. It allows the user to skip a sequence file from automated analysis, but the chromatogram is still visible.
  3. User may adjust the location of maps, files, color settings etc.
  4. Naming of the samples is now automated and can be fully customized. SBTengine will recognize the sample name of all selected samples at once (we have succesfully renamed ~1.500 sequencing files without user intervention)
  5. Near allele matches are now clearly indicated with a "tool tip" which becomes active after allele assignment and pops up when the mouse hovers over the table with crucial positions.

Improvements

  1. Many alleles differ only at the DNA level, without causing a change at the amino acid level. This also includes differences in the intron regions that do not affect the splicing event. A user may toggle whether to see these types of silent/intron ambiguities or not.
  2. After approving the allele assignment the user is requested whether to review the XML file. The user may toggle this question on or off.
  3. Older Pharmacia ALF files may be exported as Staden SCF files in the "upright" mode. These files can now be analyzed and modified by SBTengine.
  4. IMGT/HLA sequence database version 2.11 has been included
  5. DRB1, DRB3,4,5 typing has been streamlined.
  6. Webhelp manual has been adjusted
  7. Several other features were adjusted to provide more speed and control to the user

Fixed bugs

  1. Selection of nucleotide position has been adjusted such that the cursor now will jump to the position according to the IMGT/HLA database. Negative numbers will be considered as belonging to the intron region.
  2. Last visited position is now functioning.
  3. Several minor bugs were fixed.

Known Issues

  1. MRR may be limited in function for SCF files (Licor Biosciences and Pharmacia ALF).
  2. Although the XML files is a comprehensive report from SBTengine®, we are working hard to get more alternative report forms that are easier accessible to the average SBTengine user. We expect to have alternatives reports available for the end of year 20o5. Users are asked to send their request how they would prefer their report.
