Hi,
I just installed the latest mzR (version 2.23.1) to open a compressed mzML file. Before this version, I used to get the error (#170 and #229 ) related to Invalid cvParam accession, which has been fixed (Thanks a lot). I get a new error due to compressed data:
> mz <- mzR::openMSfile("file.chrom.mzML")
Error: Can not open file file.chrom.mzML! Original error was: Error in pwizModule$open(filename): [IO::HandlerBinaryDataArray] Unknown compression type.
> devtools::session_info()
mzR 2.23.1 2020-09-10 [1] Github (sneumann/mzR@39380f5)
I see that pwiz module does have the numpress related code. I am not sure if there is any disconnect related to compression in mzR. Once I decompress, it can be easily accessed using mzR, however, the file size is twice as big now.
