Error in parallel::mclapply #21

Hi Authors!!

I am trying to use this package. When I run the exemplary command in R i.e. search.dbgap("Jackson") it throws the following error:

Error in parallel::mclapply(mc.cores = getOption("mc.cores", parallel::detectCores()),  : 
  'mc.cores' > 1 is not supported on Windows

Please help me understand how to deal with this?

Hi @Rohit-Satyam , thanks for reaching out.

unfortunately this package was developped with unix systems in mind. Since the mclapply function from the parallel package relies on the fork mechanism of *nix operating systems, it does not work on windows.

I would advise you to try to use the Windows Subsystem for Linux (untested). If that doesn't work, I'm afraid you will need to find a Mac / Linux system to run the app.

Good luck!
