Picard MergeBamAlignment error - record in unmapped BAM is not second of pair

Question

[freuv1]

Hi,

I am using Picard MergeBamAlignment to merge an unaligned BAM (uBAM) file with an aligned SAM file.

I used ValidateSamFile and FixMateInformation to edit mate pair errors in the uBAM and SAM files.

However, the following is the error I keep running into:

Exception in thread "main" net.sf.picard.PicardException: Second record in unmapped bam is not second of pair: ST-K00112:15:HKFFTBBXX:1:1101:10003:16084

I then ran ValidateSamFile on the uBAM and it yielded several errors that were one of the following:

Both mates are marked as first of pair Both mates are marked as second of pair

Please advise how I can rectify this.

Your version of picard too old: should be picard.PicardException ( https://github.com/broadinstitute/picard/blob/master/src/main/java/picard/PicardException.java )
