Based on a quick search on Serial EM CCD, I suggest you check with folks
that provide the software at the University of Colorado, Boulder.
https://bio3d.colorado.edu/SerialEM/
Can you read the original data files with the latest version of their
software? Can you export from the data files to TIFF or any other format
using the latest version of their software? Have you followed their
error reporting procedure?
I am of course assuming this is the software that you are using since
you did not specify that in the email to the list.

Hi all,
I have a collection of TIFFs from some microscope imaging, but several of them
can't be opened or otherwise manipulated, showing instead this error when I
investigate them using LibTIFF in MobaXterm:
MissingRequired: TIFF directory is missing required "StripOffsets" field.
These TIFFs were collected during one imaging session with the same program
(SerialEM), and the StripOffsets error is distributed among the TIFFs seemingly
randomly. As in 10 are OK, then 50 aren't, then 10 are OK, etc.
With the suggestion of our "IT guy", I am using LibTIFF to try to attempt a repair after he confirmed that the files
weren't corrupted. It was recommended that I take the StripOffset values from the "working" TIFFs and move that value
over to the "broken" TIFFs, but I can't figure out how to begin to approach that (if it is possible). I have attached
some information from a "working" TIFF from the "tiffinfo" command as a txt file. I hope that helps.
To summarize, here is my question:
Is it possible to copy the StripOffset information from the "working" TIFFs to the
"broken" TIFFs to (hopefully) allow them to be decompressed for viewing?
Best regards,
Cole Bourque
