Description

Hi,
I'm trying to use the --map2slim functionality to map a gaf-file to metagenomics slim. It' s 90+ GB in size. The process owltools starts swapping and dies at 0,5 TB (Yes, Terabyte) memory usage. Any way around this (except splitting my file into X pieces after prototyping size vs. memory usage)?

Research direction

Start by reproducing the OWLTools --map2slim run with a representative GAF file and record memory use as the input grows. Trace the map2slim entry point to determine whether the 90+ GB input can be processed without exhausting memory; done means a verified implementation change or a documented supported limitation and workaround.
