如何在没有 GUI 的情况下使用 SPM 分割脑组织？

Question

我们正在尝试使用 SPM 对脑组织类型进行分割，几乎不可能在网上找到如何在不使用 GUI 的情况下调用其底层 matlab 函数。

我发现的一些资源没有帮助：

• SPM Manual
• SPM Book on Wikibooks

如果您知道如何在 gui 中调用 spm 函数，我的同事向我展示了如何调用它们。转到 GUI 并从菜单中选择保存脚本。这会导致以下代码在两个单独的文件中进行分段：

工作.m

matlabbatch{1}.spm.spatial.preproc.channel.vols = {'c:\test.nii,1'};
matlabbatch{1}.spm.spatial.preproc.channel.biasreg = 0.001;
matlabbatch{1}.spm.spatial.preproc.channel.biasfwhm = 60;
matlabbatch{1}.spm.spatial.preproc.channel.write = [0 0];
matlabbatch{1}.spm.spatial.preproc.tissue(1).tpm = {'C:\Program Files\spm12\tpm\TPM.nii,1'};
matlabbatch{1}.spm.spatial.preproc.tissue(1).ngaus = 1;
matlabbatch{1}.spm.spatial.preproc.tissue(1).native = [1 0];
matlabbatch{1}.spm.spatial.preproc.tissue(1).warped = [0 0];
matlabbatch{1}.spm.spatial.preproc.tissue(2).tpm = {'C:\Program Files\spm12\tpm\TPM.nii,2'};
matlabbatch{1}.spm.spatial.preproc.tissue(2).ngaus = 1;
matlabbatch{1}.spm.spatial.preproc.tissue(2).native = [1 0];
matlabbatch{1}.spm.spatial.preproc.tissue(2).warped = [0 0];
matlabbatch{1}.spm.spatial.preproc.tissue(3).tpm = {'C:\Program Files\spm12\tpm\TPM.nii,3'};
matlabbatch{1}.spm.spatial.preproc.tissue(3).ngaus = 2;
matlabbatch{1}.spm.spatial.preproc.tissue(3).native = [1 0];
matlabbatch{1}.spm.spatial.preproc.tissue(3).warped = [0 0];
matlabbatch{1}.spm.spatial.preproc.tissue(4).tpm = {'C:\Program Files\spm12\tpm\TPM.nii,4'};
matlabbatch{1}.spm.spatial.preproc.tissue(4).ngaus = 3;
matlabbatch{1}.spm.spatial.preproc.tissue(4).native = [1 0];
matlabbatch{1}.spm.spatial.preproc.tissue(4).warped = [0 0];
matlabbatch{1}.spm.spatial.preproc.tissue(5).tpm = {'C:\Program Files\spm12\tpm\TPM.nii,5'};
matlabbatch{1}.spm.spatial.preproc.tissue(5).ngaus = 4;
matlabbatch{1}.spm.spatial.preproc.tissue(5).native = [1 0];
matlabbatch{1}.spm.spatial.preproc.tissue(5).warped = [0 0];
matlabbatch{1}.spm.spatial.preproc.tissue(6).tpm = {'C:\Program Files\spm12\tpm\TPM.nii,6'};
matlabbatch{1}.spm.spatial.preproc.tissue(6).ngaus = 2;
matlabbatch{1}.spm.spatial.preproc.tissue(6).native = [0 0];
matlabbatch{1}.spm.spatial.preproc.tissue(6).warped = [0 0];
matlabbatch{1}.spm.spatial.preproc.warp.mrf = 1;
matlabbatch{1}.spm.spatial.preproc.warp.cleanup = 1;
matlabbatch{1}.spm.spatial.preproc.warp.reg = [0 0.001 0.5 0.05 0.2];
matlabbatch{1}.spm.spatial.preproc.warp.affreg = 'mni';
matlabbatch{1}.spm.spatial.preproc.warp.fwhm = 0;
matlabbatch{1}.spm.spatial.preproc.warp.samp = 3;
matlabbatch{1}.spm.spatial.preproc.warp.write = [0 0];

runjob.m

nrun = 1;
jobfile = {'c:\job.m'};
jobs = repmat(jobfile, 1, nrun);
inputs = cell(0, nrun);
for crun = 1:nrun
end
spm('defaults', 'FMRI');
spm_jobman('run', jobs, inputs{:});

您可以让脚本编辑 job.m 文件，然后运行 ​​job.m 文件。
