Problems with picard markduplicates

Question

[Cecelia]

Hi, I was running picard markduplicates with a few bam files.

java -jar /sw/bioinfo/picard/2.20.4/rackham/picard.jar MarkDuplicates INPUT=sorted.bam OUTPUT=md.bam METRICS_FILE=duplicate.txt READ_NAME_REGEX=null REMOVE_DUPLICATES=true CREATE_INDEX=true

And I got no output file and message like this:

INFO    2019-11-20 02:53:04 MarkDuplicates  Start of doWork freeMemory: 2037715440; totalMemory: 2058354688; maxMemory: 28631367680

The reference genome is the output from LINKS v1.8.7. The header of each contig should look like this: (scalfold,size,contig infomation)

>scaffold1,8899378,f8056Z8899378
>scaffold2,7251368,f8058Z7239915k15a0.13m100_f1079z11453
>scaffold3,6336565,f8055Z6291785k21a0.14m100_r10570z44780

If it is the problem with the header, how should I change it without losing information?

I read in this post that setting READ_NAME_REGEX=null could solve the problem but did not work in my case.

Any comments or suggestion will be appreciated.

Try adding a comma to the second part of the regex (full regex would be '[0-9A-Za-z!#$%&+./:;?@^_|~-][0-9A-Za-z!#$%&*+./:;=?@^_|~,-]*' and using that as the READ_NAME_REGEX
