trans interaction #160

Hello, trans interaction analysis should use the following model. python3 -m tensorqtl ${plink_prefix_path} ${expression_bed} ${prefix} --covariates ${covariates_file} --interaction ${interactions_file} --best_only --mode trans But when I tried to analyze it, I found that the error message kept showing can't allocate memory: you tried to allocate 742739225424 bytes. Error code 12 (Cannot allocate memory) Although I increased the memory to very large, I would like to ask if the trans interaction analysis requires a large amount of memory? Thank you in advance

Yes this can produce very large outputs/memory requirements depending on the inputs, but this seems excessive. How large are your inputs?
