This will get ALL your image and processed data on to your computer at you lab/office.
If you don't want it ALL, then append the directories you DO want and only those will be transferred.

Assume your username is "mcfuser"

1) Logon to your office/lab computer
2) mkdir  ???  for where you want to put your data
3) cd          to that directory
4)  issue this command:
 
 rsync -avz mcfuser@gateway.bl831.als.lbl.gov:/data/mcfuser/sub_dir/date_collected/ .
 
(note the "." at the end!  You'll need the mcfuser password, too:-)

 
Same thing for processed data, but after you have "cd" in the directory where you want your PROCESSED data stored, do this:(use "home" instead of "data")
 
 rsync -avz mcfuser@gateway.bl831.als.lbl.gov:/home/mcfuser/sub_dir/date_collected/ .
