hi
i need to open raw scan (something.1sc), edit it and save it as tif, ps or *whatever* supported by gimp.
the scan was taken on densitometer GS-710 that communicates with Quantity One software under windows and i dont'k know whether the .1sc format is supported under linux
thanks
Heleen

If this is the same .1sc format, you may be able to use the netPGM package.

Raw image files
BioRad has two different proprietary image formats: one for their microscopes and one for their gel documentation scanners. Tnimage supports reading of the 16-bit images (.1sc format) from Bio-Rad scanners. Since BioRad does not release their file format specification, the implementation is probably not perfect, and it is not possible to create 1sc format images. Depending on how the image was scanned, the contrast in the image may need to be increased before the image is visible. Occasionally the program may guess wrong about the byte order. This will cause the Bio-Rad image to appear to be composed of grainy black and white pixels. If this happens, click ``Swap image bytes'' and read the image again.
The BioRad microscope format is not readable directly, but can be converted to the supported PGM format by a utility called bioradtopgm, which is part of the NetPBM package.

Looking further, I found references to tnimage. This is an image process program that is often used for analyzing medical and astronomical images.

You can download it from: ftp://sunsite.unc.edu/pub/Linux/apps/graphics/misc/
