Hi folks,
I finally managed to identify the problem. As i said in my previous email i
tried a tif image with only a signe channel:
[EMAIL PROTECTED] SPOTS]$ ls *
-rw-r--r-- 1 david bioinfo 9,1M Jan 23 12:19 532.tif
-rw-r--r-- 1 david bioinfo 9,3M Jan 23 12:20 635.tif
-rw-r--r-- 1 david bioinfo 20M Jan 23 12:21 All.tif
CY5 image
[EMAIL PROTECTED] SPOTS]$ identify 635.tif
635.tif TIFF 1604x5108 1604x5108+444+100 PseudoClass 65536c 16-bit 9.20849mb
Cy3 image
[EMAIL PROTECTED] SPOTS]$ identify 532.tif
532.tif TIFF 1604x5108 1604x5108+444+100 PseudoClass 65536c 16-bit 9.02034mb
[EMAIL PROTECTED] SPOTS]$ identify All.tif
All.tif[0] TIFF 550x1429 550x1429+0+0 PseudoClass 65536c 16-bit 19.8007mb

All.tif[3] TIFF 1604x5108 1604x5108+444+100 PseudoClass 65536c 16-bit

The experiment is a CY5 channel scan. Well the size of the single CY5 tif
image is (1604*5108).
The same for the CY3 image.
The multi-image tif file returns 2 sizes (1604*5108 and 550*1429). With that
being said i would say the problem comes from base to handle multi-file
generated by genepix. It seems that base is reading the tif file
sequentially and therefore get wrong coordinates for the Cy5 channel (base
takes 550*1429 whereas the correct coordinates are 1604*5108).
I guess this is the problem.
I would say that at some point base needs to make the difference from
genepix multiple-tiff files and single tif files.
When I use the single CY5 image everyting works fine !!!
What do you think ?
