Error while "estimating weights from target"

[ishwarvh]

Hello,

Thanks for developing the too. I receive the following error when I run the scID_multiclass function with estimate_weights_from_target = TRUE

Stage 2: Estimate weights of signature genes from target
Error in file(file, if (append) "a" else "w") :
cannot open the connection
In addition: Warning message:
In file(file, if (append) "a" else "w") :
cannot open file 'aux': Invalid argument

I thought the issue might have been with my target dataset, so I tested with your example dataset and was able to reproduce it.

Googling the error shows that this might be an issue with setting/changing the file path of the output and input files. However, I doubt this is the cause because, if I set estimate_weights_from_target = FALSE , I am able to run the scID_multiclass` without any errors.

I was wondering if you or anyone else has come across this error and has a possible solution.

Thank you,
Ishwar
