What should my ALFF, fALFF, reHO and FC results look like after DAPRSF processing

Submitted by aminuj on

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. 

I carried out an analysis of the control group first and wanted results for ALFF, fALFF, reHO and FC, after DPARSF did all its processing, I was left with the results folder, that contained 4 folders for ALFF, fALFF, reHO and FC. 
My  FC folder is empty for some reason (anyone know why?). The files in my ALFF, fALFF and reHO should fmri in were black and white, which left me a bit confused. I assumed there would be coulours which indicated the different fluactions/activity of the brain. Is there another step I must carry out to carry out in order for colours to be seen? or Where ave I gone wrong.

Also can anyone suggest a manaual that goes through all the steps od DPARSF with a samaple R-fMRI data and explains how to intereperate  thr results? The tutorial videos on this site, don't actaually show the process of getting results from the analysis.

I've also attached a screenshot,  of my ALFF, fALFF and reHO results respectively, (should there be colour?)

regards..

Hi Jamiu,

Firstly, maybe you can attach the screenshot of DPARSF window so that we can see how you run the data. I'm not sure why your FC folder is empty but I guess may be you forget to define ROIs. Secondly, the black and white problem is likely to due to colorbar. I noticed that you were using SPM12 to check your results. I recommend you to use DPABI_VIEW (just type this in matlab command window). This may simply solve the black and white problem.

Presently we are working on the tutorials, it is coming soon :) 

Best!

Thank You for your reply,
So I think you are right, I didn't define a ROI for the FC section. How do I define a ROI? (we are looking at at the septal nuclei).
I viewed my ALFF and reHO results in DAPBI_VIEW and it is still colourless, there was an error message which came on matlab reagarding colour, I will add a screenshot of it.
Also I will add a screenshot of what the ALFF image looks like as well as my DPARSF window.

(the screenshots are added to the initial post!)
