[Brains-users] Can't open trimodal images!

[Greg Harris]

You seem to be having trouble with the automatically generated file 
names that are picked for 'b2 load image' to assemble.  As a 
work-around, you should always be able to give a Tcl command like

b2 load image {first_file_name second_file_name third_file_name}

You see, the image loading command assembles a 3-channel image from a 
list of three filenames.
