fail to open file - bwa mem using CWL

Hi,

I am trying to run simple two step CWL workflow, using v1.0. Step 1: Create sequence dictionary for reference Step 2: Align input fastq reads with reference

Step1 runs fine but step 2 (bwa mem) throws the following error:

However, I have tried running bwa mem locally (i.e. the tool itself with out cwl) and it runs fine. Wonder if it is some path issue with docker ? or cwl?

Any help will be much appreciated. Thanks.

It looks to me like the path /Users/sehrish/Google Drive/AnalysisGalaxyCpipeCWL/GATK-worflow/v1.0/Fastq-files/FQ_1_small.fastq is not accessible from within the docker container. You might want to specify that FQ_1_small.fastq is an input file so that it will be mounted into the container.

Thanks for the reply. I have solved this issue by making some changes in the yaml file for workflow. I was not specifying the input path correctly in the job file and had some issues in specifying the array of files as input to bwa-mem. It's finally resolved :)
