Dear REST team:
While I was working with the DPARSF software I was facing few problems. I am using the data having three subjects. The data is sorted and anonymised and .dcm files are put in a folder Funraw which is inside Analysis folder. While processing the data, the conversion of EPI DICOM to NIFTI is been done successfully.
i) While removing first 10 time point, error is occuring. The dialog box is showing "Error in Removing First 10 time point".

Here we release some demonstrational data for resting-state fMRI:
FunRaw -> Functional DICOM data
T1Raw -> Structural DICOM data
DPARSF_Preprocess_ALFF_FC.mat -> Parameters for DPARSF to preprocess the raw data and calculate ALFF/fALFF/Functional Connectivity
DPARSF_ReHo.mat -> Parameters for DPARSF to calculate ReHo based on preprocessed data
Dear All,
I have to do a ALFF analysis on fMRI images.
I used matlab 7.4. I did the preprocessing using SPM8. my smoothed images have matrix size 79 95 68 and voxel size 2x2x2. I have 195 scan for each subject.
I would like to run my analysis on a single subject. I detrend and filter the images using no mask.
I tried to use rest1.1 and 1.4, but both of them give me the following error:
error using ===> zeros
out of memory
请教在采用rest进行ReHo的ANOVA分析的时候,如何看两水平间差异。采用统计软件的时候这个很容易实现。但是,在使用rest时得到的只是一副图像,我不知道如何得到两两之间的差异,以及如何对图像进行解释。希望各位给予帮助。不胜感激!
Hello, everyone here!
We are planning to launch a resting brain fMRI research with Philips 3T MRI scanner, but we don't know how to set the parameters,
can you experts here tell me how to set the related parameters in detail? Any advise will be much appreciated! Thank you!
Dear REST team,
老师您好!
看到您的这个论坛真的是太高兴了,非常感谢您的无私奉献!
我们想请教一下philips 3T 用来做大脑的静息磁共振应该怎样设置参数比较好?
希望老师在百忙中能够指导。
谢谢!
Dear RESTers
I am new to REST and to SPM. I would be grateful for any advice.
I have resting state fMRI data (3mins, TR 3s) and I am keen to look at the ALFF in a lesion and on the contralateral hemisphere to detect any differences. For each of my scans the lesion is in a different place, difference size, and may affect either hemisphere.
If I generate the ALFF map and calculate the mean ALFF value in lesion and in a mirror region is this valid or would higher level statistics be more appropriate?
Thanks
Krishna
