chunxuqu Aug-16-02, 03:51 PM (PDT) "How big the gif file should be?" Hi, I installed SMD on a linux box (redhat 7.3). When I submitted an experiment, the gif file generated is as large as about 50MB. Is this normal? The slide has 8K spots. We used GenePix. The info from tiffinfo is as following: TIFF Directory at offset 0x5335088 Subfile Type: (0 = 0x0) Image Width: 3816 Image Length: 11432 Resolution: 2000, 2000 pixels/cm Position: 0.276, 0.056 Bits/Sample: 16 Sample Format: unsigned integer Compression Scheme: None Photometric Interpretation: min-is-black Artist: "AxImageIO: Barcode=; Temperature=27.18; FocusPosition=0" Date & Time: "2002/07/12 14:06:20" Host Computer: "AxImageIO: FullSize=4400,14300; Compression=0,100; PMT=650; Averaging=1; LaserPower=3.59; LaserOnTime=10841; ScanPower=100" Software: "AxImageIO 2.0.2.2" Document Name: "635nm image" Image Description: "532 nm " Make: "Axon Instruments (V1.00)" Model: "GenePix 4000B " Orientation: row 0 top, col 0 lhs Samples/Pixel: 1 Rows/Strip: 32 Min Sample Value: 0 Max Sample Value: 65535 Planar Configuration: single image plane Thanks, Chunxu   Alert Edit | Reply | Reply With Quote | Top

Our tif files are normally ~30MB each, and they produce a gif in the 5-10MB range, Cheers, Gavin   Remove | Alert Edit | Reply | Reply With Quote | Top

I think the resolution is too high, and changed it from 2000pixel/cm to 200pixel/cm using convert. But after run through createGIF.pl, the gif file is still the same size. I guess convert does not change the header of the original tiff info. Chunxu   Remove | Alert Edit | Reply | Reply With Quote | Top
