Hello,

I am currently studying the connection between density maps and the secondary structure elements.

I have a density map file for a certain protein, giving for each voxel a density value, and what I am missing is a "helix map", giving a binary value for each voxel, representing wether it is a part of a helix or not.

In order to build this "helix map", I need to use the .pdb file of that protein, but I am not really sure how to extract an appropriate 3D boolean matrix out of this file.

Any suggestions would be greatly appreciated.

Thanks
