Hi Sebastian, Chimera does not read maps from GRID. Here are the map formats that Chimera knows about: http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/filetypes.html#volume Because you used filename extensions we assigned to other formats as shown in that table, Chimera tried to read the file as those formats (which it is not, hence the errors). Also, I do not know what is happening with your chimera-users subscription - maybe try to sign up again? http://www.cgl.ucsf.edu/ mailman/listinfo/chimera-users/index.html Best, Elaine ----- Elaine C.

Dear Elaine,

I posted a message in the mailing list – and got the answer I wasn’t member, though I am?! So I just send it once more, directly to you, because you answered * very * helpful last time ;-)

Message was: Hi All,

I try to import a contour map generated with GRID and saved as *.grd or *.cnt file. Trying to open th e*.grd file in chimera I get the error message

Opening I:\strukturen\prep_modTemp\1j1b_DRY.grd I:\strukturen\prep_modTemp\1j1b_DRY.grd: UHBD file does not contain integer value 1 at bytes 96-99 using either little or big endian byte order. Found 46146 Done opening I:\strukturen\prep_modTemp\1j1b_DRY.grd

With *.cnt I get ‘file not found’, because file is supposed to be a *.bmp.

Does anybody have an idea, how to open my nice GRID contour map? Greetings Sebastian

Thanks in advance Sebastian
