TargetTR not working for UKB

[yli091230]

The current TargetTR wdl files are not working under UK-Biobank. I'm noticed some missing parameters in the "targetTR_launcher_ukb.py" file but still got the following error messages after fix those:
A job in the job tree named "mergestr" running function "main" of "mergestr" failed because of AppInternalError: job script function run_command exited with permanent fail code 1 sys.exit(run()) File trtools trtools mergeSTR mergeSTR.py , line 670, in run retcode = main(args) File trtools trtools mergeSTR mergeSTR.py , line 632, in main current_records = mergeutils.InitReaders(vcfreaders) File trtools trtools utils mergeutils.py , line 399, in InitReaders return [next(reader) for reader in readers] File trtools trtools utils mergeutils.py , line 399, in <listcomp> return [next(reader) for reader in readers] StopIteration

I tested the older version of workflow on DNANexus and able to get it work.

Not sure if this is due to the mergeSTR or changes in wdl files.
