Tesseract .tr file empty - homebrew

I'm trying to integrate text recognition into my app with TesseractOCR. I need it to learn a custom font. I have Tesseract installed on my Mac via Homebrew. I have a tiff file: eng.scout-cond.exp0.tiff that I'm converting into a ".box" file. When I run the command
tesseract eng.scout-cond.exp0.tiff eng.scout-cond.box nobatch box.train.stderr
It says Tesseract Open Source OCR Engine v4.1.1 with Leptonica
Then generates a file called eng.scout-cond.box.tr
I don't understand why it's a .tr extension instead of the .box extension shown to me in tutorials.
When opening the .tr file in a text editor, it's empty.
What would be causing it to be empty?
eng.scout-cond.exp0.tiff
The tutorial I'm following

I missed a step, the command shown in the original post is to create a .tr file from the .box file and the .tiff file.
SOLUTION:
I used the command tesseract eng.scout-cond.exp0.png eng.scout-cond.exp0 batch.nochop makebox
To make the .box file. Then I ran the command in the original post.

How to open .sav extension IDL file imageJ?

I have a stack of images. These images are the IDL output with the .sav extension. I couldn't find a jar file that supports this in imageJ. How do I open these images in ImageJ?
It looks like this is possible using OME Bio-Formats, with a script:
https://docs.openmicroscopy.org/bio-formats/5.9.2/users/idl/index.html?highlight=idl
Edit: this link describes how to read images into IDL, the OP was asking for the opposite.

Can't convert .obj files to the new .usdz format

when trying to convert my .obj files to .usdz using command line, I can't find the generated file.
Screenshot showing the command line is not generating the file
I got a message saying the file was generated with success, but there's no generated file at all. :(
What I've done so far:
Updated my Xcode to Version 10.0 (10A255)
Updated 'USD' path environment variables, following USDPYTHON documentation. (export PATH=$PATH:/USD
export PYTHONPATH=$PYTHONPATH:/USD)
Using macOS High Sierra 10.13.6
Any clues on any step I missing to successfully convert a model to .usdz?
Note: When using a 3rd party tool, like https://vectary.com for example, I'm able to convert my .obj model.
Thanks!

Training Tesseract ocr using jTessBoxEdit

Hi i want to generate tesseract OCR training data file(tessdata). I'm using jTessBoxEditor tool(On Mac Os) for achieving this, but i have no idea how can i use this tool.And further i use the tessdata file in my ios application.
I'm also searching for this i share the links with you
http://vietocr.sourceforge.net/training.html
http://code.google.com/p/tesseract-ocr/wiki/TrainingTesseract3
but i have no luck :( . So please share the links which provide detail/steep by by steep implementation of training file(teasdata file).
Here is the download for the tess files
http://code.google.com/p/tesseract-ocr/downloads/detail?name=tesseract-ocr-setup-3.02.02.exe&can=2&q=
I'm on the same page as you with getting this to work. Here is the tut im using.
http://www.resolveradiologic.com/blog/2013/01/15/training-tesseract/
I have learned that you need a .tif file with a .box file in the same folder to load the boxes.
For Example
testdata.tif
testdata.box
anotherExample.eng.tif
anotherExmaple.eng.box
To create box files easily if you don't know how do this after you download and install the tesseract files.
->Open command prompt and CD to your tesseract file, which is usually in your programfiles/Tesseract-ocr folder
-> Run Box creator tesseract C:\location of the tif file\thetiffile.tif C:\location of the tif file\thetiffile.tif
batch.nochop makebox
and that should spit out the box file you need.
I'm in the process of going through and discovering. I will keep you updated. If you have any other issues let me know and maybe I can help.
You'll have to build or install all the Tesseract training executables first. Then inside jTessBoxEditor, set the appropriate Tesseract Executable location.

Integrate Tesseract OCR engine in iOS?

I am integrated Tessertact Engine in iOS. I used the following tutorial for integration. My code having no error use-tesseract
but i am getting the following error when i run the application
According with your error.
The file is being compiled instead of being copied to output bundle.
Therefore, make sure that in project settings file just copied, not compiled.
Also select that file & make its property as text file, or pure data - in such case it wouldn't be processed by external tool.

Is there a way to teach tesseract for iOS a new font?

Im currently using tesseract for iOS using Nolan Brown's example. It works ok, but I need it to start picking up a new font (which I have in .tff format) which will always be numbers.
I have found questions on StackOverflow about tesseract learning fonts which all point to the google guides on how to teach Tesseract a new font using command line. But I'm already using a compiled copy of the lib from Nolan's example.
How can I teach tesseract a new font? Will I need to recompile the lib for iOS? How do I do this?
You might try training a new "traineddata" file using these instructions.
