[BioC] analyzing HumanHT12 with lumi

Wed Sep 9 09:01:53 CEST 2009

 Hello Amit,

 first thank you very much for your response!

 I included the the TargetID column and tried to run the lumiR function 
 with all options available but the result is still the same.

 test <- lumiR(file = "D:/Programme/eclipse/tmp/FinalReport.txt", sep =
 "\t", detectionTh = 0.01, na.rm = TRUE, convertNuID = TRUE, lib.
 mapping = NULL, dec = '.', parseColumnName = TRUE, checkDupId = TRUE, 
 QC = TRUE, columnNameGrepPattern = list(exprs='AVG_SIGNAL', se.exprs='
 BEAD_STD', detection='DETECTION', beadNum='Avg_NBEADS'), inputAnnotatio
 n=TRUE, annotationColumn=c('PROBE_SEQUENCE'), verbose = TRUE)

 I also pre-processed a Mouse WG-6 chip (V2) and everything is fine 
 there: no duplicated IDs or “Inf” in the quality control.

 Maybe there is a problem with the HumanHT12 chip?

 Does anyone else have any advice?

 Thanks again!

 Kind regards,

 Steffi
