FRAME_SUBPATH = leginonframes
52
</pre>
53
In this case, you will need to create a directory called leginonframes on your Falcon image storage server (called OffloadData on your scope PC) with these parent directories
54
<pre>
55
OffloadData\TemScripting\BM-Falcon\leginonframes
56
</pre>

This leginonframes directory can then mounted on your permanent storage system and allow rawtransfer.py to rsync the files.
