Hi everybody, our team (Lapsyde, Laboratory for the Psychology of Child Development and Education, Paris, France) have some questions about DPARSF toolbox and bandpass filtering for ReHo analysis.
Hi,
as I see, DPABI has the option to calculate measures like ALFF in native space and then to normalize the derivates and smooth the derivatives. On which article or method is this based on?
greetings
David
Dear readers,
I am wondering about the following circumstance:
I realigned my fMRI-images with DPARSF (s. realigned_image) but now I noticed that their orientation (anteriro-posterior) does not match that of the SPM template used for normalization (SPM_template). Is that a mistake of my own or does DPARSF change this orientation difference during normalization?
with kind regards
Markus Loose
Dear all,
Thank you for the great toolbox. I am new at using DPARSF and I am still trying to familiarize with it.
Hi everybody, i've some questions about DPARSF and the frequency range which is selected for processing :
Q. 1 : If I want to chose a specific frequency band for ReHo analysis (like in this paper : doi:10.1371/
p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 7.0px Helvetica}journal.pone.0086818.: IMF1 : (0.1-0.25 Hz), IMF2 (0.1-0.04 Hz)...), is this filter has to be used (cf screenshot) ?
Dear Chao-Gan,
I have examined ALFF abnormalities in two type of patients and I would like to examine the shared abnormalities. Acctually, I have tried to use SPM to do a conjuntion analysis, but SPM seemed to require the spm.mat file which I did have, so I was wondering that can I achieve this goal using DPABI?
Best,
Vincent
Dear Dr. Yan,
first of all, thank you for the wonderful tools you have created, which provide a great service to our community.
Hi,
Sorry to bother you again. I performed ANCOVA analysis with dpabi and obtained 10 nii images including the F.nii map. But I cannot view the results of F.nii using dpabi viewer. Some parameters of the F.nii can be viewed in dpabi viewer overlay list (see below).
Hi, we are using your toolbox DPARSFA (v4.2) with matlab R2014b
We followed the tutorial concerning the folder structure.
We selected this parameters :
When we compute the data, we have the following error message :
