RealignerTargetCreator - lines without interval

LilyLily Member Posts: 12

I ran the GATK RealignerTargetCreator command and got an output file with some lines in non-interval format (about 6%).
For example: the line chrM:125-346 versus the line chrM:7684
When I ran the next IndelRealigner command it failed with the following error message, indicating the line without interval:
"##### ERROR MESSAGE: Invalid argument value 'targetIntervals' at position 10.

ERROR Invalid argument value 'GRC13283077_var_list' at position 11."

What is the reason for this output? What can I do about it?
Please advice.

    Hi @Lily,

    Actually chrM:7684 is a valid interval. Your problem is probably a typo in your command line, as the "invalid argument value" error occurs when the command is being parsed, not during execution. Can you please post your complete command line?

    Thanks for the very prompt reply. You were right, it was just a typo... Thanks!!
    I hope it is OK that I'll take this opportunity to ask one more question:
    In the log followed the RealignerTargetCreator, I got the following messages:

    INFO  15:14:53,687 TraversalEngine - Total runtime 6209.96 secs, 103.50 min, 1.72 hours

    INFO  15:14:53,691 TraversalEngine -   -> 10 reads (0.00% of total) failing UnmappedReadFilter

    Are these percentages reasonable?

    No problem. The numbers you're getting for DuplicateReadFilter and MappingQualityZeroFilter are rather high. This is not unusual, but the Broad's Genomics Platform labs have put a lot of effort into developing procedures that minimize wasted sequence, so we typically see much lower numbers. You may want to discuss this with whoever produced the sequence data.
