For your information:

The unit fragment length (UFL) and the unit genome position (UGP)
annotation files for the Affymetrix GenomeWideSNP_6 chip type has been
updated, and available at:

  http://aroma-project.org/chipTypes/GenomeWideSNP_6

The source was the two Affymetrix NetAffx CSV files
GenomeWideSNP_6.cn.na30.annot.csv (777MB) and
GenomeWideSNP_6.na30.annot.csv (1.32GB).

The updates are only minor from previous versions.  More details below.

HISTORY:

# UGP:
# o na27.1 -> na30
#   No differences
# o na27 -> na27.1
#   No differences
# o na26 -> na27
#   Two units (932039, 1872834) where moved from ChrX to ChrY.
#   Same location.
# o na24 -> na26
#   Only minor modifications for non-missing values:
#   - three loci changed chromosomes
#   - an additional 23 loci changed positions, of which only 17 moved
#     more than 2 base pairs.

# UFL:
# o na27.1 -> na30
#   - No changes.
# o na27 -> na27.1
#   - No changes.
# o na26 -> na27
#   - No changes.
# o na24 -> na26
#   - All changes are for SNP units.
#   - There are 6 NspI and 14 StyI changes in SNP fragment lengths,
#     which some are only minor.
#   - There are 1108 more SNPs that now have missing values.
