Hello. I have a stack of intensity images (8bit) taken from confocal microscopy of dapi expression in Drosophila that I'd like to visualize. I cannot figure out the format that the volume viewer requires to view the data; more specifically, none of the formats in 'registered file types' are familiar to me and I've been unable to find anything about them to sort out which format I should convert to. I have read the image sequences into matlab (3d matrix) and can write output to just about anything from there if I know the format. Does anyone have an idea for what the best/easiest/only format I should use? A pointer to a spec on the format if it's not something trivial (like matlab 'save stack.txt varname -ascii') would be appreciated. If it makes a difference, at some point soon I'd like to visualize more channels that just dapi (dll, for example) simultaneously. Thanks in advance. I really do appreciate it! -William ------------ William Beaver wbeaver@cs.ucsd.edu
