I would like to add more details to Bruno's answer on how to save to external file.
In Python/YADE you can use the command WRITE(), let's say you create a variable 'a' to store your data's info:

a=open('allinfo','w') #allinfo is the name of the file, w is write
permission

Then do the loop as Bruno mentioned:

for b in O.bodies:
  a.write(str(b.state.pos[0]), str(b.state.pos[1]), str(b.state.pos[2])+'\n')

a.close() #close the file

Check in the folder where you launch this script, the file should be
'allinfo' which contains the data you need, line by line. Then load it
in to excel or matlab or whatever for post processing.

My other advice is to save anyway the full model (xml.gz) so that you can recall more data later on. You won't know what data you'll need more in the future, better save them all.
Anyway keeping the data as txt/csv is a good idea, since maybe you can work with it in Windows other time. This might be not ideal but that's what I did during my thesis and it's just fine.

Hien.
