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.
INFO: Care must be taken to thoroughly inspect your data when using -gcut. In particular, inpsect the edges of gm and cerebellum for over-aggressive cutting. Add -segmentation brainmask.gcuts.mgz to tkmedit to view the voxels which gcut has removed.

-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):
