error on mclapply(1:nrow(count), function(ii) {: 'mc.cores' > 1 is not supported by Windows

Dear Author of the CellTran Package,

I am writing to express my appreciation for your work on the CellTran package, which I find to be an incredibly valuable tool for my research.

While using the package on a Windows system, I encountered an issue when calling one of its functions. The error message I received was：

transcell <- CellTran::transition_index(sce.tumor)
error on mclapply(1:nrow(count), function(ii) {:
'mc.cores' > 1 is not supported by Windows

It appears that the function relies on mclapply, which unfortunately is not supported on Windows for mc.cores > 1. I understand that this limitation stems from how parallel processing is implemented on Windows systems, but I was wondering if there might be a parameter or an alternative approach within CellTran to address this issue.

If the package does not currently support an alternative for Windows users, could you please advise on how best to adapt the code for this environment?

I greatly appreciate your time and assistance in addressing this matter, and I am truly grateful for the effort you have put into developing CellTran. Thank you for considering my question, and I look forward to hearing your advice.

Best regards
