Hello,
I encountered yet another error. For some subjects DPRSFA shows me a warning message saying "The detected time points is 2, it is different from the predetermined time points (260), check your data!". The problem is that my data has 260 volumes so I don't understand the meaning of this. Does anyone have an idea?
Thank you so much!

请教，想在写脚本的时候，直接调用dpabi中的 Imgcalc 做一些图像计算，不知该调用哪个函数合适，多谢！

An error occur when I using ROI signal extracter:
Dear Dr YAN
please How many number of voxels (cluster size) should I put in the red box in below picture????
Dear Dr YAN
After cluster report , we have this table:
for example in cluster one we have only one region(Cerebelum_Crus2) with peak mni coordinates(-36 -78 -45) and peak value(4.2667).
Dear Dr YAN
after FDR coreection I get these result for Alff and fAlff
we notice that the activation region in Alff more than activation regions in fAlff
this because the Alff range is more than fAlff(fraction of Alff), and Alff senestive to physiological noise .
my question does this reason right or wrong? if it is true there is any mor reasons for this result?
thanks for your help.
I extracted 116 ROI region signal applied by AAL mask, but I need voxel-wise information.
I knew that functional information comes from grey matter, so I'm gonna extract all voxel signals in grey matter.
