Name

mri_make_template

Purpose

This program reads surface and curvature data from multiple subjects and produces a "template". This template is later used by ["mris_register"] to register the sphere surface of individual subjects to the average surface.

Note: Descriptions below refer to "atlas", following the usage in this program's source code and some of its messages. However, the file produced by this program is normally referred to as a "template" file, as distinct from "atlas" which is generally used for the GCA files that capture parcellations. (See ["mris_ca_train"].)

Synopsis

mri_make_template [Flagged args] hemi sphere_name subject1 [subject2 ...] template_name

Arguments

Positional Arguments

Posn

<Argname>

Description

1

<hemi>

lh or rh

2

<sphere_name>

Name of sphere surface to read from each subject. Actual filepath will be:BRBR{subject}/surf/{sphere_name}.{hemi}

3 to last-1

<subject>

List of one or more subjects whose sphere files will be input.

last

<template_name>

Name of template. If template already exists, it will be input, used to register subjects and new variables will be added to it. If it does not exist it will be created, and initial data created from the first subject.

Required Flagged Arguments

None

Optional Flagged Arguments

Category

Flag

<Args>

Description

Input

-sulc

<othercurv>

Sets curvature_names[1] (of 0..2) to othercurv. Default is 'sulc'.

Input

-infname

<surffilename>

Sets surface_names[0] = surffilename, and curvature_names[0] = surffilename'.H'. Default is 'inflated'. (Not sure what a '.H' file is or where it comes from. --GW).

Input

-O

<surface_name>

Sets a different surface_name for surface_names 1 and 2 (of 0,1,2), instead of default smoothwm.

Input

-overlay-dir

<overlay_dir>

Sets directory from which to read optional overlay file. Default 'label'.

Input

-sdir

<subjects_dir>

Set SUBJECTS_DIR to subjects_dir

Atlas config

-addframe

<which_field where_in_atlas>

Uses the two integer args to specify how to add a variable to the atlas.BR BRwhich_field specifies the variable to add, with the meaning of the number determined by the list you can get from the vector option.BRBRwhere_in_atlas tells what order to place the new field/ Locations 0..2 are already occupied by the default variables.

Atlas config

-nodefault

Not sure the purpose of this option --GWBRBRbase_default=0;BRBRatlas_size = 0;BRBRparms->nfields=0;BRBRfor (n=0;n<3;n++)BRBRInitFieldLabel(&parms->fields[n]);

Atlas config

-overlay

<overlay_file>

Increases atlas_size by one (to makes space for additional atlas variable) and reads overlay file from {subject}/label/{overlay_file}. To change directory, use -overlay_dir option

Atlas config

-size

<atlas_size>

Sets the atlas to be able to contain data for atlas_size number of variables for each vertex. Default is atlas_size=3.

Algorithm

-A

<navgs>

Average curvature patterns navgs times

Algorithm

-annot

<annot_name>

Zero the median wall. Ie: Causes program to read annotation file from which to find vertices that belong to the medial wall so that these can be given a curvature of zero. Rationale?

Algorithm

-median

Using median normalization (default is mean)

Algorithm

-nbrs

<nbrs>

Set neighborhood size to nbrs

Algorithm

-norot

Help/usage info for this is wrong (--GW):BRBRUsage: -norot : 'align before averaging'BRBR-norot printout: 'not aligning hemispheres before averaging'BRBRWhat source code appears to do:BRBRIf -norot is selected, program appears to skip performing rigid alignment of subject's surface to template before averaging.BRBRThis appears to be the default, which is surprising because in addition to the Usage info describing this option wrongly, Usage does not mention the '-rot' option.

Algorithm

-rot

-rot printout: 'rigidly aligning hemispheres before averaging.' BRie: DO perform rigid alignment of subject's surface to template before averaging.BRBRWhat source code appears to do:BRBRFor multiframes situation: always perform rigid alignment.BRBRFor NOT multiframe situation: perform rigid alignment for all subjects except for the first. (Presumably the first subject is used to create the initial template data?)

Algorithm

-S

<scale>

Scale 'parameterization' by scale (float). (If 'parameterization' refers to a complete surface worth of per-vertex values (ie: an atlas variable), is the idea here to scale all those variables by the same amount? --GW)

Utility

Utility

-vector

Prints some help for using Multiframe mode. Option presumably named 'vector' because multiframe mode means that the template has multiple values per vertex.

Utility

Utility

-W

<optional int>

Obsolete option. Ignored.
