Hi , I am trying to read affymetrix tiff images. As you said before I printed the tiffinfo. It gave like this: sample.tif: Warning, invalid TIFF directory; tags are not sorted in ascending order. sample.tif: Warning, TIFF directory is missing required "StripByteCounts" field, calculating from imagelength. TIFF Directory at offset 0x8 Image Width: 4733 Image Length: 4733 Bits/Sample: 8 Compression Scheme: None Photometric Interpretation: min-is-black Image Description: "[30..46140] PGA-HCL-astM_atop-10aUA-s2:CLS=4733 RWS=4733 XIN=3 YIN=3 VE=17 2.0 09/04/02 15:32:34 \024 \024 HG-U133A.1sq \024 \024 \024 \024 \024 \024 \024 \024 \024 6" Planar Configuration: single image plane my tiff image is sample.tif. from the above I understood that my tiff image doesn't use any compression. It also says single image plane. In the above output what does XIN and YIN and VE mean? Now can you explain me with a program(if possible) how to read the image data? one more doubt is in the above output where should i look for the type of image like is it scanline-based or strip based or tile based? Thanks, Sridhar!!
