Re: PDx-Pop 4.20 Update Now Available
Hi everyone
I am trying to build a model for a multiple dose oral drug. I am not sure
how to arrange my input data file. If anyone has done that could he please
send me his data file or part of it just to see how is the data arranged and
what I need to include.
Regards
Mariam
