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
