What exactly is your question? How to implement this algorithm? How to acquire this fMRI data?

I acquired dataset from ADNI. Now I have to classify this into AD/nonAD class. Can you tell me how to preprocess the data and how to extract features from data. The paper says that fmri images are converted into a graph and then graph features are extracted from it. How can this be done

Could you be more specific? Are you unclear of how the algorithm works? Have you tried to implement this algorithm in software and are having difficulty with it?

I have no prior experience in neuroimaging and I want to start with this paper. I don't have any idea about how to start implementing this. I want a step by step procedure to implement this paper.

This really isn't the site to give you a step-by-step procedure. We'll be happy to help you once you've chosen a software package, started analysis and then have questions!

# How to convert fmri brain volumes to brain graph

(Asked by: username_0 on 2017-03-24)

I am working with fMRI data of Alzheimer's Disease (AD) patients. I want to convert brain volumes to brain graph and then using different graph metrics, I want to classify the brain volumes in AD and non-AD class.
The paper I want to implement is "[Automatic classification of Alzheimer's disease with resting-state fMRI and graph theory](https://www.ncbi.nlm.nih.gov/pubmed/25907414)".
