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.

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?

No. That might have worked on uncompressed files but your tiffinfo output shows LZW compression which means the offsets will be different for every file.

The output of tiffinfo and tiffdump on one of your broken files might allow someone to give you better suggestions. But I suspect fixing the files will be quite difficult unless you can find software already written for that purpose.
