Hi，
I am writing to seek your assistance with an issue I have encountered while using the iWhale pipeline. It is a highly efficient tool, and I appreciate its capability to manage reanalysis seamlessly from the point of failure.
However, I have encountered an error, the details of which are as follows:

scons: Reading SConscript files ...
scons: done reading SConscript files.
scons: Building targets ...
scons: building `VCF/Combined_VCFs_by_sample/T_N_merged_indels.vcf' because it doesn't exist

From my preliminary investigation, it appears that the issue might be related to GATK3 not recognizing the VCF file. I am not sure how to modify the command in docker pipeline. I would greatly appreciate it if you could provide some guidance on how to resolve this matter.
