NDPI to TIF

Postby swvanderlaan » Mon Jan 30, 2017 11:56 am

Hi,

We're using a new Hamamatsu C12000-22 scanner to scan our slides. The output is .NDPI. I'm now trying to convert this to proper TIF files that can be handled by our downstream pipeline (https://github.com/bglnelissen/slideToolkit).

I've found a tool NDPITools which seems to do the job in theory. I use the following command:

Code: Select all
for FILE in $(ls); do echo "* Processing sample [ ${FILE} ]."; ndpi2tiff -t ${FILE} ; done


It seems to work just fine. But when I now use 'slideThumb' from 'slideToolKit' it throws an error:

Code: Select all
MissingRequired: TIFF directory is missing required "TileOffsets" field.


I understand this actually originates from 'LibTIFF': http://libtiff.maptools.org/man/TIFFReadDirectory.3tiff.html.
So, I guess 'openslide' now doesn't understand these newly created TIFF-files because the tiles are there, but it is unclear how they relate to each other? Or am I misinterpreting the error?

Can anyone perhaps give a pointer as to how to solve this issue?

Thanks!

Sander

Hi,

your interpretation of the error is probably correct as some IFD is missing a tag preventing OpenSlide from operating on the file. `tiffinfo -s` could give extra diagnostics about the strip offsets and sizes. As this is a third party tool, you might want to report the issue directly to the maintainer of the NDPITools.

As an alternative for converting NDPI images to TIFF, have you tried using Bio-Formats and more specifically the bfconvert utility? It is routinely used by several people in our community and I also expect the output to have been used by applications like OpenSlide.

Best,
Sebastien

Thanks for the confirmation. I have the suspicion that perhaps this information is already missing in the NDPI file. Or do you think that is impossible?

Does
Code: Select all
bfconvert
work on NDPI files? If so, I will certainly give that a try.

Thanks again

bfconvert works with all file types supported by Bio-Formats.
