we found that there are about 8-9% of all probesets in the hgu133a package for
which no information on chromosomal location (i.e. base pairs from the
telomere) is available.
However, other public databases like Golden Path offer start and end positions
for each probeset on the array. What is the reason for this discrepancy ?
What are the paths AnnBuilder uses in order to map probeset-IDs to chromosomal
Would it be safe to use chromosomal locations obtained from other sources
directly instead of relying on the hgu133a package ?
