FreeSurfer Tutorial: Useful recon-all flags.
This page extends ReconAllDevTable. The following flags can be used in conjunction with individual steps or the entire process:
-autorecon-all |
either of these flags will work to run the entire recon-all process. |
||||
-all |
|||||
-dontrun |
useful for debugging. just prints the commands that will run (does not execute them). |
||||
-clean-tal |
trashes any manual edits to the talairach, makes talairach.xfm and talairach.auto.xfm the same and runs using the automatically generated talairach.xfm |
||||
-clean-seed |
trashes all saved seed point for the cutting planes and uses the automatically set cutting planes. |
||||
-clean-cp |
trashes control points and runs the normalization without control points. |
||||
-clean-bm |
trashes any manual edits to the brainmask.mgz volume, makes brainmask.mgz and brainmask.auto.mgz the same and runs using the automatically generated brainmask.mgz |
||||
-clean-wm |
trashes any manual edits to the wm.mgz volume and runs using the automatically generated wm.mgz. |
||||
-clean-aseg |
trashes any manual edits to the aseg.mgz and runs using the automatically generated aseg.mgz |
||||
-clean-cpwm |
combination of -clean-cp and -clean-wm. |
||||
-clean-xopts |
|||||
-clean-cw256 |
|||||
-clean-lta |
|||||
-clean-pfh |
trashes preflood height volumes (skullstrip) |
||||
-clean-bfse |
trashes edits to brain.finalsurfs.manedit.mgz |
||||
-clean |
use this flag to clear all of your manual edits and run it completely fresh. |
||||
-noaseg |
use this flag on subjects that either cannot use an aseg (i.e., baby brains or non-human primates) or for those for which you will never want an aseg. It skips the subcortical segmentation and will not try and use it (aseg.mgz) in any of the subsequent steps. |
||||
-norandomness |
use this flag on a subject when it is necessary to ensure that results are exactly the same from run to run. it seeds the random number generator used by some algorithms with the same number, removing any variability. |
||||
-notal-check |
use this flag when running a subject after receiving an error about Tailarach Failure Detection and the tailarach transform looks fine after checking it with this command line: tkregister2 --mgz --s <subjid> --fstal |
||||
-gcut |
use this flag when skull strip leaves a little bit of dura behind. In this case, adjusting the watershed parameters won't be as useful and manual edits will take too long. |
||||
-surfsegedit |
this flag fixes the gm and a few other areas in the aseg using info from the surfaces. Run after the surfaces are done. |
||||
-multistrip |
use this flag on a subject when you would like to get skullstrip results using several different watershed preflood heights simultaneously. Output will be nu, orig, and T1 volumes stripped at these heights: 5, 10, 20, 30. You can change which preflood heights are used by setting this variable first: setenv WATERSHED_PREFLOOD_HEIGHTS '20 30 40 50'. Be sure to use -clean-bm with this flag. |
||||
-deface |
removes the face from the orig volume to anonymize it. |
||||
-vno_match_check |
Confirms that the surface data is out of sync in case an error indicates that there is a size mismatch. Then run from whatever stage that is out of sync. |
recon-all flag |
Used with step |
Description |
-no-ca-align |
-careg |
this flag should be used if the data to be processed comes from the same scanner platform and pulse sequence as the atlas. With the FreeSurfer RB40 atlas this means MPRAGE on a 1.5T Siemens scanner. |
-calabel |
||
-subcortseg |
-gcareg |
runs the subcortical segmentation and associated statistics |
-canorm |
||
-careg |
||
-rmneck |
||
-skull-lta |
||
-calabel |
||
-segstats |
||
-cc-xyz <X Y Z> |
-fill |
manually sets the corpus callosum seed point |
-pons-xyz <X Y Z> |
-fill |
manually sets the pons seed point |
-rh-xyz <X Y Z> |
-fill |
manually sets the right hemisphere seed point |
-lh-xyz <X Y Z> |
-fill |
manually sets the left hemisphere seed point |
-jacobian_dist0 |
|
Computes how much an individual surface must be distorted in order to perfectly match the atlas (ie, distance contraints are turned off). |
-old-atlas |
||
-gcareg |
Use this flag in conjunction with other steps of recon-all and it will default to the old set of atlases. Uses talairach_mixed.gca for the subcortical segmentation, ?h.average.tif for the surface morph, and ?h.atlas2002_simple.gcs for the cortical parcellations. |
|
-canorm |
||
-careg |
||
-calabel |
||
-surfreg |
||
-contrasurfreg |
||
-avgcurv |
||
-cortparc |
The following flags can be used after certain manual intervention to regenerate accurate volumes and surfaces (if a data set has or needs spherical morphing, add the -autorecon3 flag):
