Hello Guys,
I have couple of questions regarding DPARSF, to understand I used the demo data dor DPARSF, the questions are as follows:
how can we skip the Pre-processing step once it was already done? I’m interested in repeating the FC calculations without repeating the extensive and cumbersome preprocessing, which can be done only once.
hey guys, I am looking to do a FC analysis of my data set, 2 groups healthy and mild alzheimers.
However when processing with DPARSF, i get an error after the normalise: estimate and write part,
The essor appears is something to do with a colour bar, i'm not exaclty sure how it wants me to 'add the colour bar'.
If anyone has had past experieneces with this please help me, I have looked through the forum and no one has really explained/answered how to fix this issue. This issue has been very frustrating and i'm wasting a lot of time trying to fix it.
hey everybody,
I am trying to extract the ROI signals for a lot of objects, I used DPARSF to do so, now that I am almost finished with the preprocessing steps, I found out that since I am working in ubuntu, I had to install FSL. The preprocessing took several days to complete for me, and I need to know if my results are accurate or if I should install FSL and run the preprocessing steps again.
Thank you very much for your time.
Dear Chao-Gan and other experts,
Hi All,
I am an Intern and so I am new to matlab and DPARSF, so basically I have been given 2 sets of fmri data to anaylyze, one from an Alzheimer's group the other a control group.
Hi All,
I am having an issue when calling up the DPARSF program on matlab. When I type in the command DPARSF , I get an error message exactly as follows,
When processing my data for one subject, I ended up with a lot of noise in the FunRawARglobalCWS folder when I expected the data to be cleaner. Does this have something to do with the fact that the NIFTI files are in 4D rather than 3D? I attached a screenshot of the image below. The DPARSFA settings that I am using are also attached. When reorienting the functional and T1 NIFTIs, my process is to put in -45 and -25 to center the image on the viewer then pressing "Reorient", is this correct? Final question: can you tell me what each of the folder-names mean?
Dear experts,
I am trying to perform an ALFF analysis with dpabi. I want to introduce the GM volume as a covariate in the two-sample t-test.
I think that I have to introduce this covariate in "covariate images" option in the statistical analysis, but What kind of images should I use?
I have the segmented and dartel images for all subjects, but I don't know if these images are the correct ones.
Best,
Juan
Dear experts
I preprocessed dicom files from FunRaw to smoothed ReHo image by DPARSF. The whole process was error-free, but the bottom regions of the szReHo image including cerebellum and pons were shown as black. I think there was a problem with preprocessing, but I do not know exactly what the problem is. I attached files created during preprocessing. I would like to ask you for your expert advice. Thank you
