Empty file at Foo.list7

[evolscientist]

I'm repeatedly running into an error with ORP2.3.1

make: *** [/nobackup/rogers_research/HybridRNASeq/DyakubaReference_carcass_M_ORP2.3.1/assemblies/diamond/DyakubaReference_carcass_M_ORP2.3.1Out.list7] Error 1
make: *** Deleting file `/nobackup/rogers_research/HybridRNASeq/DyakubaReference_carcass_M_ORP2.3.1/assemblies/diamond/DyakubaReference_carcass_M_ORP2.3.1Out.list7'

This happens most often at list7 but occasionally with other list files. It appears to occur only when the list file is empty and no items match the search criteria. I can coerce the program to run by running the grep command from the make file on the command line.

grep -xFvwf ${DIR}/assemblies/diamond/${RUNOUT}.list6 ${DIR}/assemblies/diamond/${RUNOUT}.list5 > ${DIR}/assemblies/diamond/${RUNOUT}.list7

This creates an empty file with the same file name. Then I rerun ORP and it will run to completion.

This has happened with multiple data sets for very different species. I don't know if there might be factors from our HPC settings that cause it to fail to create the file or if it's a product of the code itself. It isn't holding back my work at the moment, but I thought I should report it.
