Hi,
First of all, thank you for the great tool!
I am looking for a way to use the features extracted with extract_features_fp.py. Ideally, I would like to use them together with some clinical data to train a mache learning classifier (random forest, xgboost or something like this).
However, since the number of features extracted is different between images, I am unsure how to reduce the number of features of the h5 files into something with a common shape for all images used. I was thinking of using PCA for this but I would like to know if you have any previous experience on this or you have a better idea.
I am also aware that you developed PORPOISE and I am planning to give it a try but the number of samples is rather small (~250) and maybe this method would need more samples to generalize.
