Hi Julio,

  I can write some Python code that will allow Chimera to read the
"TOM toolbox for Electron Tomography" format.  Is this format used
with other software?  Can you provide me an example file?  What is the
typical file suffix?

  For an example file you can email me something under 5 Mbytes, or
put it on the web or an ftp site for me to download.

  I don't see any header parameters that indicate xyz pixel sizes
in nanometers.  This is useful in Chimera if you are for example docking
crystal structures.  If it isn't available I can just open the data in
Chimera with pixel sizes defaulting to 1.

  I also don't see a field that encodes byte order.  The machine coding
field (Mac, PC, SGI, ...) is not a good way to deduce byte order, but
maybe it is the best info available in the header.

  I don't understand the comments about "abandoned header".  It sounds like
this means there is no header on certain files.  Chimera won't be able to
read those.
