AFNI program: SurfInfo
Output of -help
Usage: SurfInfo [options] <surface>
surface: A surface specified in any of the methods
shown below.
Optional Params:
-detail DETAIL: 1 = calculate surface metrics.
-debug DEBUG: Debugging level (2 turns LocalHead ON)
Specific Info: Using any of these options outputs values
only for the specified parameters.
-N_Node: Number of nodes
-N_FaceSet or -N_Tri: Number of triangles.
-quiet: Do not include name of parameter in output.
-sep SEP: Use string SEP to separate parameter values.
Default is ' ; '
Specifying input surfaces using -i or -i_TYPE options:
-i_TYPE inSurf specifies the input surface,
TYPE is one of the following:
fs: FreeSurfer surface.
If surface name has .asc it is assumed to be
in ASCII format. Otherwise it is assumed to be
in BINARY_BE (Big Endian) format.
Patches in Binary format cannot be read at the moment.
sf: SureFit surface.
You must specify the .coord followed by the .topo file.
vec (or 1D): Simple ascii matrix format.
You must specify the coord (NodeList) file followed by
the topo (FaceSetList) file.
coord contains 3 floats per line, representing
X Y Z vertex coordinates.
topo contains 3 ints per line, representing
v1 v2 v3 triangle vertices.
ply: PLY format, ascii or binary.
Only vertex and triangulation info is preserved.
mni: MNI .obj format, ascii only.
Only vertex, triangulation, and node normals info is preserved.
byu: BYU format, ascii.
Polygons with more than 3 edges are turned into
triangles.
bv: BrainVoyager format.
Only vertex and triangulation info is preserved.
dx: OpenDX ascii mesh format.
Only vertex and triangulation info is preserved.
Requires presence of 3 objects, the one of class
'field' should contain 2 components 'positions'
and 'connections' that point to the two objects
containing node coordinates and topology, respectively.
gii: GIFTI XML surface format.
Note that if the surface filename has the proper extension,
it is enough to use the -i option and let the programs guess
the type from the extension.
-onestate: Make all -i_* surfaces have the same state, i.e.
they all appear at the same time in the viewer.
By default, each -i_* surface has its own state.
For -onestate to take effect, it must precede all -i
options with on the command line.
-anatomical: Label all -i surfaces as anatomically correct.
Again, this option should precede the -i_* options.
Specifying surfaces using -t* options:
-tn TYPE NAME: specify surface type and name.
See below for help on the parameters.
-tsn TYPE STATE NAME: specify surface type state and name.
TYPE: Choose from the following (case sensitive):
1D: 1D format
FS: FreeSurfer ascii format
PLY: ply format
MNI: MNI obj ascii format
BYU: byu format
SF: Caret/SureFit format
BV: BrainVoyager format
GII: GIFTI format
NAME: Name of surface file.
For SF and 1D formats, NAME is composed of two names
the coord file followed by the topo file
STATE: State of the surface.
Default is S1, S2.... for each surface.
Specifying a Surface Volume:
-sv SurfaceVolume [VolParam for sf surfaces]
If you supply a surface volume, the coordinates of the input surface.
are modified to SUMA's convention and aligned with SurfaceVolume.
You must also specify a VolParam file for SureFit surfaces.
Specifying a surface specification (spec) file:
-spec SPEC: specify the name of the SPEC file.
Specifying a surface using -surf_? method:
-surf_A SURFACE: specify the name of the first
surface to load. If the program requires
or allows multiple surfaces, use -surf_B
... -surf_Z .
You need not use _A if only one surface is
expected.
SURFACE is the name of the surface as specified
in the SPEC file. The use of -surf_ option
requires the use of -spec option.
[-novolreg]: Ignore any Rotate, Volreg, Tagalign,
or WarpDrive transformations present in
the Surface Volume.
[-noxform]: Same as -novolreg
[-setenv "'ENVname=ENVvalue'"]: Set environment variable ENVname
to be ENVvalue. Quotes are necessary.
Example: suma -setenv "'SUMA_BackgroundColor = 1 0 1'"
See also options -update_env, -environment, etc
in the output of 'suma -help'
Common Debugging Options:
[-trace]: Turns on In/Out debug and Memory tracing.
For speeding up the tracing log, I recommend
you redirect stdout to a file when using this option.
For example, if you were running suma you would use:
suma -spec lh.spec -sv ... > TraceFile
This option replaces the old -iodbg and -memdbg.
[-TRACE]: Turns on extreme tracing.
[-nomall]: Turn off memory tracing.
[-yesmall]: Turn on memory tracing (default).
NOTE: For programs that output results to stdout
(that is to your shell/screen), the debugging info
might get mixed up with your results.
Global Options (available to all AFNI/SUMA programs)
-overwrite: Overwrite existing output dataset.
Equivalent to setting env. AFNI_DECONFLICT=OVERWRITE
-ok_1D_text: Zero out uncommented text in 1D file.
Equivalent to setting env. AFNI_1D_ZERO_TEXT=YES
-Dname=val: Set environment variable 'name' to value 'val'
For example: -DAFNI_1D_ZERO_TEXT=YES
-Vname=: Print value of environment variable 'name' to stdout and quit.
This is more reliable that the shell's env query because it would
include envs set in .afnirc files and .sumarc files for SUMA
programs.
For example: -VAFNI_1D_ZERO_TEXT=
-all_opts: Try to identify all options for the program from the
output of its -help option. Some options might be missed
and others misidentified. Use this output for hints only.
-h_find WORD: Look for lines in this programs's -help output that match
(approximately) WORD.
-h_view: Open help in text editor. AFNI will try to find a GUI editor
on your machine. You can control which it should use by
setting environment variable AFNI_GUI_EDITOR.
-h_web: Open help in web browser. AFNI will try to find a browser
on your machine. You can control which it should use by
setting environment variable AFNI_GUI_EDITOR.
-skip_afnirc: Do not read the afni resource (like ~/.afnirc) file.
-pad_to_node NODE: Output a full dset from node 0 to MAX_NODE-1
** Instead of directly setting NODE to an integer you
can set NODE to something like:
ld120 (or rd17) which sets NODE to be the maximum
node index on an Icosahedron with -ld 120. See
CreateIcosahedron for details.
d:DSET.niml.dset which sets NODE to the maximum node found
in dataset DSET.niml.dset.
** This option is for surface-based datasets only.
Some programs may not heed it, so check the output if
you are not sure.
-pif SOMETHING: Does absolutely nothing but provide for a convenient
way to tag a process and find it in the output of ps -a
-echo_edu: Echos the entire command line to stdout (without -echo_edu)
for edification purposes
