p670 users,
AIR 5.2.5 is now available on the p670 under /usr/local/AIR5.2.5. For those of you who would like to use AIR for motion correction, I wrote a script called motioncorrect that simplifies the process.
Usage Info:
motioncorrect [-Dv] [-i input] [-r rundir] -b bxhfile
-D debug mode, only prints configuration information
-v verbose mode
Usage Example:
[dias@volta: /data] motioncorrect -Dvi Test.01/20030410_04498/ -b run004_02.bxh -r run004_02
Note the following: - The resulting air004_02 directory is at the same level as the original run directory.
e.g. from the above example: Test.01/20030410_04498/air004_02. - Default values for derivation of registration parameter file are as follows:
- uses rigid body 6 parameter model for 3d model
- cost function: least squares with intensity rescaling
- threshold of a 1000 for std file and reslice file
- For those of you who don't need the above helper script, see AIR man pages http://bishopw.loni.ucla.edu/AIR5/howtomri.html for detailed option information.
For more script help, motioncorrect -h at the prompt.
For those of you who do not have access to the p670 and are interested in obtaining the motioncorrect source, email me at dias@biac.duke.edu. |
