  • Empty sequence dictionary

    Hi.

    When I used picardtools ValidateSamFile, it reported the empty sequence dictionary error in sam file. What does this error mean?

    Wish help! Thanks very much in advance!

    Are there no @SQ lines in the SAM header?

      Hello Everyone,
      I am having trouble converting the sam files to bam using samtools. I used this cmd to convert my sam to bam -

      samtools view -bT hg19.fa s_chip2.sam > s_chip2.bam
      I got this error.
      Parse error at line 7707082: sequence and quality are inconsistent
      Aborted


      I ran ValidateSamFile.jar, a picard tool and got the following error, hundreds of them -

      WARNING: Read name HWI-ST798R:82: D18MUACXX:2:1101:2025:1987, A record is missing a read group
      ERROR: Record 5, Read name HWI-ST798R:82: D18MUACXX:2:1101:8625:1992, Empty sequence dictionary.

      I am not sure how to fix this, any help is appreciated.
