Picard Tools Markduplicates 'No Group 1' Error

Hi all,

I am getting a funny error and can't figure out what the issue is:

I have no idea about Java so help appreciated. Seems to be a find/replace error in general (from Google) but I do not see where that is happening in markDuplicates. I give it a regex for the read names (format= HWI-ST0988:234:C1MAUXR:3:1131:7638:2239), but that is validated and correct (AFAIK!). I am using output from the latest stable version of STAR (2.3.0) which is apparently importable to Picard.

java -jar ~/bin/picard-tools-1.93/MarkDuplicates.jar I=./Aligned.out.sam O=./Aligned.rmdup.sam M=./pic.met REMOVE_DUPLICATES=TRUE AS=TRUE READ_NAME_REGEX="[a-zA-Z0-9-]+:[0-9]+:[a-zA-Z0-9]+:[0-9]+:[0-9]+:[0-9]+:[0-9]+" VALIDATION_STRINGENCY=LENIENT

Thanks,
Bruce.

you need to specify a regular expression group (= specify the parenthesis) in your parameter: READ_NAME_REGEX

Example:

"[a-zA-Z0-9]+:[0-9]:([0-9]+):([0-9]+):([0-9]+).*

Hi Pierre, thanks for the answer, thought it was something horrendously complicated, had tried all combinations of the REGEX I give above but the parentheses caught me out. Need them around numeric ([0-9]+) but not on the alphanumeric. Appreciate your response. Bruce.
