Hello, I am receiving a bug when extracting the ROI signals (i.e white matter, CSF) for the nuisance covariates regression. The error appears after slice timing, realignment have been done. The error I received is below, I believe it is due to DPARSFA not being able to find the masks in the working directory. The error only appears with DPARSFA.
I was wondering if there is a tool in REST we could use to carry out mixed effects analyses?
do you guys know what the problem is here?:
Read 3D EPI functional images: "/SCR2/REST/FunImgsym/WY1K".
??? Error using ==> reshape
To RESHAPE the number of elements must not change.
Error in ==> y_VMHC at 75
I get the following error message running the ALFF computation in DPARSF:
Read 3D EPI functional images: "/SCR2/REST/FunImgCWS/WY1K".
Load mask "".
Performing FFT .............
First thanks you for your great work!!
I performed a multiple regression analysis in SPM8 with a behavioral score as vector for a resting state task.
Then I performed the Alphasim test with T treshold at 0.005 rmm at 3 (for 3x3x3) and here is my doubt.
Dear DPARSF users,
I was wondering if DPARSF is converting the fmri signals from arbitary scanner uints into percentage signal change during the processing step.
I will appreciate it if you can let me know.
Thanks in advance !!
I am new in REST software and i want to apply one sample and two sample t-tests on obtained ALFF maps.
When I apply t-test from statistical analysis section, Matlab meets error (' rest_Fix_Read_Write_Error'). I applied every instructions that were mentioned in this forum before but it makes no difference.
I am running only motion regression in DPARSFA and looking at the output it appears that the image is demeaned. Does it not output the functional image with the mean added back in order to use it for further processing?
