How cross-platform compatible is it? NOT.
We have the same issues. What you can do is use symbolic links to
"fool" the paravision system, and move the files/directories wherever
you want.
%> cd /opt/PV3.0.2/username
%> ln -s ArchiveDir nmr [now paravision will store data in ArchiveDir
- we do this for everyone so that they all use the same folder]
Then...
%> cd ArchiveDir
%> mv RB1006_17.Xz0 /where/I/really/want/the/data/RB1006_17
%> ln -s /where/I/really/want/the/data/RB1006_17 RB1006_17.Xz0
Of course you can automate this using shell-scripts, etc.
