Picard SortSam error Unrecognized tag type
I'm running several samples through a pipeline and using Picard 1.80 and Java version 1.7.0_51. Most of the samples are running fine but I got this error message for two of the samples: net.sf.samtools.SAMFormatException: Unrecognized tag type: # (the tag type was ^^ for another sample).
I'm using SORT_ORDER=coordinate. The bam file from the last step seems to be okay as seen with samtools flagstat. Is there any other way to check the inout bam file?
Searching online only gave "Unrecognized tag type: B", which seems to be resolved in Picard 1.5 version. So I don't know why I'm getting this error!
