Neuroimaging normalization

Hello ,

How can i normalize this two modalities in a common space , i used preprocessing.StandardScaler() but it doesn’t give good results…?
thank you

OK, “preporcessing” means different things in different contexts. Here you probably need to do a spatial normalization (ie spatial alignment of your image to a stndard brain template, such as MNI152) that is performed in tools such as fmriprep.
So my best advice is to start by running preprocessing e.g. with fmriprep.
