Hello,

Could suggest some tools that are best suited for HAMMER related segmentation.

Thank you.

Hi Vidya,

Depending on your data, it may be simple to use fsl's fast in
combination with the command changelinevalueinimg included in the HAMMER
distribution. The latter will simply change the default segmented values
to those in the convention that we described in the manual.

the commands can be something like this:

Command: fast -t1 -c 3 -n -v5 -or -od fast1 subject.T1.byte_cbq.img
Command: fast -t1 -c 3 -n -v5 -or -od fast2 fast1_restore.img
Command: fast -t1 -c 3 -n -v5 -or -od fast3 fast2_restore.img
Command: changelinevalueinimg fast3_restore.img fast3_restore.img -o83
-c10
Command: changelinevalueinimg fast3_restore.img fast3_restore.img -o249
-c150
Command: changelinevalueinimg fast3_restore.img fast3_restore.img -o166
-c250

Hope this helps,

Andres

Hello Andres,

I did use FAST to segment my data. My particular questions are:

1) Can I proceed segment the data without special attention to the ventricles?

2) This question has already been asked before: I do not have a binary for changelinevalueinimg. Is there somewhere I can download it from?
