[Bioc-sig-seq] ShortRead qa() no longer working

[Dario Strbenac]

Hello,

I've updated my ShortRead and IRanges packages recently and the qa function doesn't work for me anymore. It spends a couple of minutes processing, then fails with an error :

> str(path)
chr "C:/Users/dario/Documents/Garvan/rawData/seq/Ramaciotti/25-03-2010/s_1_1"

> dir(path)
[1] "12627LN-FFPET_MBD2IP_1.Rdata"    "12627LN-FFPET_MBD2IP_1.wig.gz"   "12627LN-FFPET_MBD2IP_1_GR.Rdata" "mapping.log"                     "s_1_sequence.fastq.gz"           "s_1_sequence.uniq.map.gz" 

> QAfastq <- qa(path, "fastq.gz", "fastq")
Error in stop(msg, " ", errors, domain = NA) : 
  no function to return from, jumping to top level
Error in slot(object, ".srlist") : 
  cannot get a slot (".srlist") from an object of type "NULL"
In addition: Warning message:
UnspecifiedWarning

  UnspecifiedError: qa(readFastq(dirPath, pattern, ...), pattern, verbose = verbose)
 error in evaluating the argument 'dirPath' in selecting a method for function 'qa'

Could this be a bug in the function ?
