I am running Picard to get alignment stats on my bam file. However, I am getting the following error

The command I am running is

Any help you can provide would be greatly appreciated, Ann

It looks like the quality scores in your BAM are out of the range of what the tool can handle. Can you please paste the output of the following command?

samtools view /mnt/twin/Rust/SWS484SPF_PBJ_ScaffoldsF500_compare_to_PST_sorted.bam | head

I want to take a look at the quality score strings in your BAM.

I had the same error, using samtools view mysorted.bam | head | cut -f 5

the quality result

60 60 60 60 0 60 60 60 60 39

any clue?

Those are the MAPQ scores for the read. I'm suggesting that the ASCII-encoded Phred quality scores are out of range. I'm basing that on the source, specifically the collectQualityData method referenced in the trace.

Would you mind posting the output of your command, minus the cut?

Hmmm, there are no ASCII-encoded per-base quality scores in the result. I wonder if that's the problem. Here's what a read with those present would look like:


Two questions:

-Does your job fail immediately?

-What aligner are you using?

ADD REPLYlink written 23 months ago by Dan D6.8k

the job fail immediately, aligner bwa-mem, the aligned reads were fasta reads no quality associated with it (actually it is contigs)

I think the most likely explanation for the failure is the asterisk in place of the quality scores, which is a result of feeding FASTA data into the upstream alignment process. This is based on @Medhat 's information, the name of the BAM in @mia 's listed command which contains the word "scaffold", and the information in the stack trace combined with examination of the source.

I did some digging around and found some more examples to support this notion. Based on the discussions in the link, it seems like a way to make this tool work with your data is to generate a copy of the BAM using the "PrintReads" tool with the --default-base-qualities parameter. This will insert dummy per-base quality scores and allow the tool to execute. Of course, you shouldn't trust any metric which relates to per-base quality, but everything else should be legit.

ADD COMMENTlink written 23 months ago by Dan D6.8k

based on this answer: java -jar ~/source/GenomeAnalysisTK.jar -T PrintReads -R genome.fa -I contig_sorted_RG.bam -o contig_sorted_rg_fake_quality.bam --defaultBaseQualities 1

and continue to the other step normally and it succeeded.

So I would say this is the correct answer (at least in my case I can not accept it of course)
