I was able to successfully build a .blib file from the file "New TNBC_final.msf" file that you uploaded.
I just noticed that your error message is saying something about "NEW TBBC_file.pdresult". It might be that I need to see that file in order to reproduce the error that you are seeing. I was not aware that BiblioSpec knew how to read .pdresult files, but my information is probably out of date.
Here is the list of file formats that BiblioSpec knows how to build libraries from:
You can build a library from a .msf file without needing a .pdresult file.
If you send me the file "NEW TBBC_file.pdresult" I might be able to figure out what is going wrong.
