How can I compare the STRIDE and DSSP output files of a particular pdb file? I have the pdb file of H-ras protein 5P21.pdb. I am supposed to compare the output of DSSP and STRIDE files after feeding this pdb file to respective servers. My question is how to make a quick comparison between these two results?

Here a solution that does not require you to upload the files to the servers: You can graphically visualize DSSP and Stride at the Sequence Page at RCSB PDB:



"add annotation" -> Stride and look at the graphical comparison between DSSP and Stride.
