Believe the error message! It says the file is too small and it is. The grid size of 120 by 120 by 120 has over 1 million grid points but the file size is 0.5 million bytes. The smallest value format used takes 1 byte per grid point. You may have a truncated copy of the file. If the file opens on another machine, then the copy on that machine must not be truncated. Check the size of that file and make sure you get a full-size copy of it.

Hi

I'm trying to open a density map file using chimera and for some reason the file won't open. The opening is followed by an error message regarding the file size being too small for the grid size.

The same error appears also in the old version (1.4.1) and also in the newest version.

How can I solve this problem? How can I change the grid size?

The same file opens successfully on a friends computer with the 1.4.1 version and so I assume the file is not corrupted.

Attached is an image of the error message.

I'd appreciate your response.

Thank you
