My protein has few G310 helices. It is clearly visible through STRIDE or DSSP, but when i open the structure in PYMOL it didnt show it. Other visualization graphics like CHIMERA and VMD are  able to pick few of them but not all the G310 helices..For manuscript preparation i have drawn the topology diagram taking the output from STRIDE and DSSP while the overall 3D structure is from PYMOL..Will it be O.K to show some helices missing from the output of pymol while they are present in the toplogy diagrma ? or the reviewer will raise the issue? hope you are able to understand what i mean to say.
