For RESTplus, the mask folder of CSF, WM, Global mean signal is in 160122_RESTplus_V1.1\mask. 

For example:   CSF: CsfMask_07_61x73x61.img     WM: WhiteMask_09_61x73x61.img   global mean: BrainMask_05_61x73x61.img

you can use the utility of RESTplus: "Extract ROI singal", and select these mask as your ROI. select the 4d data as input.

You will get the time series. It is a series of number in txt file. However, you can plot it in RESTplus. You can plot it in other software (e.g matlab, R )

Thank you for answering, but i have a problem here
i did what you said, but i have an error about the uncompatibility of mask and data, the mask should be 64X64X48 not 91X109X91

Dear,

 

We are sorry for the delay. Time series of CSF, WM, (or/and Global mean signal) are stored in a folder named "FunImgxxxxCovs" in your data processing path.

 

With best regards,

Lei Gao.
