question: readPlinkToMatrixByIndex #14

Open complexgenome opened 3 years ago

complexgenome commented 3 years ago

Hi developer,

Thanks for this library. I would like to process data where sample size is 200K+ using following function:

readPlinkToMatrixByIndex(plinkFilePrefix, sampleIndex, markerIndex)

I would like know: Does the plink file loaded into the library first, or, there are read in chunks?

I am developing pipeline for the 200K in plink file per chromosome basis.

Thank you.
