    I have a similar same error when trying to run the same pipeline I've been using successfully for the last several years but with the RealignerTargetCreator tool.

    I've tried the same command with GATK 3.0-0, 3.8-0 and 3.8-1 all give the same error.

    Hi Mat Nightingale, the above question is for GenomeSTRiP, while it looks like your question involves GATK3. Our support team no longer supports GATK3, so for GATK3 questions we recommend asking other community members or looking for help on our legacy forum. We recommend upgrading to GATK4, we offer support and it is a great update!

    Please let me know if you have any questions.

    It is hard to say for sure what the problem is, but I would guess it has something to do with the classpath and not finding the all of the jar files. Some things you can try to get more information:

    Try to run the problematic command outside of Queue (e.g. with a script directly on the cluster) based on what Queue is running.

    Did any of the other preprocessing steps have problems? There are several other steps that should run before this, but this is the first step using reflection to find the walker to run.
