[IMP-dev] Volume calculation for an elongated protein in IMP?

Hi all,

It seems to me that the current volume calculation in IMP EM module is based on a globular protein/complex shape (assuming 1.2 cubic angstrom per dalton), not applicable to an elongated protein such as Amelogenin. I compared UCSF chimera and it reported ~half size volume for the same density map and threshold. I don't know in detail how Chimera calculates volume for the density map of an elongated protein, but it would be great if we can add this function (or any other method that we can trust for an elongated /extended protein) to IMP. Any suggestions? Thanks!
