这个错误是因为 `matlabbatch.spm.stats.fmri_spec.sess.scans` 的类型不支持使用点进行索引。你可以尝试使用大括号 `{}` 进行索引,如下所示:
```
matlabbatch{1}.spm.stats.fmri_spec.sess.scans = cellstr(spm_select('ExtFPList', curWPAT, '^sw*.nii', Inf));
```
或者,你也可以使用 `setfield` 函数来设置结构体中的字段值,如下所示:
```
matlabbatch = setfield(matlabbatch, 'spm', struct('stats', struct('fmri_spec', struct('sess', struct('scans', cellstr(spm_select('ExtFPList', curWPAT, '^sw*.nii', Inf)))))));
```
这样就可以成功赋值了。

这段代码有几个语法错误,你可以试着按照下面的修改来运行:
```matlab
clear;clc;
parentdir = 'F:\data process\fMRI\fmrioutput'; % 定义储存各被试源文件的上级文件夹
cd(parentdir); % 进入这个上级文件夹
allsubjects = dir('sub*');%查找该文件夹下的所有被试
subinfos = numel(allsubjects);
for i=1:numel(allsubjects) % 对每个被试进行循环
cursubject = allsubjects(i).name; % 找到当前被试的名字
matlabbatch=cell(1);
curWPAT = fullfile(parentdir,cursubject,'WPAT');
curfucout=fullfile('F:\data process\fMRI\fmrioutput',cursubject,'WPAT');
matlabbatch{1}.spm.stats.fmri_spec.dir = {curfucout};

matlabbatch{3}.spm.stats.con.delete = 0;
spm_jobman('run',matlabbatch);
end
```
主要的修改如下:
1. 在 `curfucout` 赋值语句的末尾加上分号;
2. 在 `matlabbatch{1}.spm.stats.fmri_spec.sess.multi` 赋值语句中,使用字符串拼接的方式来生成文件路径;
3. 在 `matlabbatch{1}.spm.stats.fmri_spec.sess.tempxx` 赋值语句中,使用 `dir` 函数来列出相关文件;
4. 最后添加了一个 `spm_jobman` 函数来运行 `matlabbatch`。

这段代码可能存在一些错误,不过我尝试理解你的意图,以下是我对代码的修改建议:
```
parentdir = 'F:\data process\fMRI\fmrioutput'; % 定义储存各被试源文件的上级文件夹
cd(parentdir); % 进入这个上级文件夹
allsubjects = dir('sub*'); % 查找该文件夹下的所有被试
subinfos = numel(allsubjects);
for i = 1:numel(allsubjects) % 对每个被试进行循环
cursubject = allsubjects(i).name; % 找到当前被试的名字
curWPAT = fullfile(parentdir, cursubject, 'WPAT');
curfucout = fullfile(parentdir, cursubject, 'WPAT');
matlabbatch = struct('spm', struct('stats', struct('fmri_spec', struct())));
% 设置输出路径
matlabbatch.spm.stats.fmri_spec.dir = {curfucout};
% 加载数据
matlabbatch.spm.stats.fmri_spec.sess.scans = cellstr(spm_select('ExtFPList', curWPAT, '^sw.*\.nii$', Inf));
% 设置时间信息
matlabbatch.spm.stats.fmri_spec.timing.units = 'scans';
matlabbatch.spm.stats.fmri_spec.timing.RT = 2;
matlabbatch.spm.stats.fmri_spec.timing.fmri_t = 16;
matlabbatch.spm.stats.fmri_spec.timing.fmri_t0 = 8;
end
```
主要的修改包括:
1. 修改了输出路径的定义,将 `curfucout` 赋值给了 `curfucout`。
2. 加入了加载数据的代码,使用 `spm_select` 函数来选择该被试的所有 sw.nii 文件。
3. 修改了 `matlabbatch` 的定义方式,使用了结构体嵌套的方式。
这样你就可以使用 `matlabbatch` 变量来进行后续的 fMRI 分析流程了。
