Tiff 'image to Stack' generation, Tag problem: unknown field with tag 50839 (0xc697) encountered

Md Tamjidul Hoque
Dear All


Problem description:
===============
     I was making multi-paged Tiff image using ImageJ (using option: Image
to Stack) to be analyzed by already developed

script in Acapella (Opera). It does not recognize the tag file ' 50839 '
added by ImageJ [Error Message: unknown field with tag 50839 (0xc697)
encountered]

and hence can not proceed.

On the other hand, other commercial Tiff image joiner/ merger does not add
that specific tag and hence Acapella

works smoothly for those images and I will be using ImageJ.



Queries:
======
(1) Looking forward for solution/suggestion.
(2) Is it possible have the 'Image to Stack' source code - so that I can
check/modify and prepare the code for batch/auto conversion of many images.
(3) Why is the tag '50839' needed?

Thanks
Tamjid

This is a bug in Acapella. TIFF readers are supposed ignore tags they
do not recognize.

Upgrade to ImageJ 1.43b, run the Image>Stacks>Images to Stack command,
disable "Use Titles as Labels" in the dialog box, and tag 50839 will
not be created when you save the resulting stack as a TIFF file.

The source for the ImagesToStack class is at
<http://rsb.info.nih.gov/ij/source/ij/plugin/ImagesToStack.java>. The
complete source for ImageJ 1.43b is at
<http://rsb.info.nih.gov/ij/download/src/>.

It is the private TIFF tag used by ImageJ to save metadata, such as
stack slice labels.

Dear Wayne

          the '50839' tag problem is over but Acapella is showing different
error: "Data item not found in the current data block".

Perhaps it is not getting the 2nd page - as I am having two image for 2
channel - channel 1 for live and channel 2 for dead

thus the complete error is appearing as:


>> Command line syntax incorrect or data item not found (_["image" &
Dead_Channel]): Data item not found in the current datablock: _["image" &
Dead_Channel] <<


Thanks
