FREESURFER SAMPLE DATA


The sample data used in the FreeSurfer workshop is contained in directory 
"lc_play".  Within lc_play/ you will find additional sub-directories, labeled
001/, 002, /003, and 004/.  

Each  numbered sub-directory contains 124 MPRAGE anat image files (I.001-I.124)

Follow the instructions in the handout "fs_doc" or in the "fs_hands-on" 
presentation (.pdf or .ppt format) on how to begin processing your data.


In addition to the sample data, there is a script included called 
@lc_play.script.  To run this script, simply type one of the following
commands:

	./@lc_play.script

OR	tcsh @lc_play.script

This script will automatically pre-process the data for you.  Specifically, it
will take the raw image files and assemble them into AFNI datasets.  Each
dataset will be intensity normalized, volume-registered, and finally averaged
together.  At this stage the final dataset is ready to be imported into 
FreeSurfer.  For further assistance, follow the instructions in "fs_doc" or 
"fs_hands-on" (.pdf or .ppt).

Finally, there is a sub-directory called lc_avg4_gold.  This contains the 
finished product that resulted from processing our datasets in AFNI,followed
by surface creation in FreeSurfer.  It's simply here for your viewing pleasure.
