Suffix option (-o) deleting input file extension for output file name, when segmenting AND reconizing a directory

[PierreYvesJallud]

Hi all,

My environment:

• kraken --version: kraken, version 5.3.0
• python --version: Python 3.11.2
• /etc/os-release :

PRETTY_NAME="Debian GNU/Linux 12 (bookworm)"
NAME="Debian GNU/Linux"
VERSION_ID="12"
VERSION="12 (bookworm)"
VERSION_CODENAME=bookworm
ID=debian
HOME_URL="https://www.debian.org/"
SUPPORT_URL="https://www.debian.org/support"
BUG_REPORT_URL="https://bugs.debian.org/"

I'm not sure it's a bug, but when I use kraken with the following conditions, the input file extension is deleted:
find pathToImgs/*.jpg | parallel kraken -I {} -o .ocr.txt segment -i mySegmentModel.mlmodel -bl ocr -m myReconizingModel.mlmodel

If the input files look like myImgFile.jpg, the reconizing output files look like myImgFile .ocr.txt (without .jpg)...
I would have expected they look like myImgFile .jpg.ocr.txt

When I proceed for a single input file, the result is good:
kraken -i myImgFile.jpg -o .ocr.txt segment mySegmentModel.mlmodel -bl ocr -m myReconizingModel.mlmodel

The result file is myImgFile.jpg.ocr.txt. The jpg extension is retained.

Is there an explanation? Did I make a mistake with the options 🤔?...

Greetings

Uhmm, this command isn't supposed to work and it doesn't on my system. `-i` is for an explicit mapping between input and output files, `-I` is for globbing multiple files and producing an output path with the suffix defined by `-o`. The stripping of the last extension is by design.

Well 🙄... this combination of parameters has been suggested in the eScriptorium forum). Except the problem of suffix, it works perfectly 😎

That's not a real obstacle for my work. I already have to modify the ALTO files (name and fileName) to integrate the result in eScriptorium and that's pretty simple with a little script. So... you be the judge =)

Yes I remmeber that thread and the commands are actually fine except that you're missing the second required part of the `-i` argument so I really got no idea how you got any file output at all with 5.3.0 (or any other version for that matter).

And yet... it turns ✨🪐✨ 🤓!
I just checked the script and I haven't made a mistake when copying the line.
