use msieve linear algebra after CADO-NFS filtering

Hello
I want to use msieve linear algebra after CADO-NFS filtering. I read readme.msieve in cado and it said:
"concatenate all the relation files specified by purge.log in
the order specified, and name the file <prefix> in the same
directory as all the other CADO intermediate files. If Msieve was
compiled with zlib support, the files do not have to be uncompressed"

which files should be concatinate? how?

cat is the command to concatenate files in linux.
If the files are compressed, zcat is the command that deals with those.
Find the relations files created by CADO (or, perhaps, find purge.log and hope it tells you which files are relations files).
zcat them all into msieve.dat, or gunzip and then cat.

The internal format CADO uses for filtering has changed since that was written, and I have not updated the Msieve code to parse the new format.
