Error for save and import

[Leehong-DENG]

Hi, I tried to run DREAM with BIDS format but failed. Here's my setting:

But there came error as following,

错误使用 save
由于 'D:\Tools\Testdata\DREAM_BIDS\DP\sub-M57900WDANYULIANG\func' 不存在，无法创建 'DREAM.mat'。

出错 DREAM_FreqCalc_IMG (line 10)
save(savep);

出错 DREAM/RunButtonPushed (line 131)
DREAM_FreqCalc_IMG(app.tr,app.workdir,app.sub_list,app.data,app.files);

Sometimes I got this error with the same settings:

错误使用 importdata (line 139)
无法打开文件。

出错 DREAM/RunButtonPushed (line 142)
csv = importdata('freqbands.csv');

错误使用 matlab.ui.control.internal.controller.ComponentController/executeUserCallback (line 382)
计算 Button PrivateButtonPushedFcn 时出错。
