combine_tessdata -e extracts the lstm file from the traineddata provided from original training by google.
----------------- tesstrain.sh it will create .lstmf files yes. these are created from the box-tiff pairs created from the training text and fonts --------------------------- lstmtraining program takes all of these .lstmf files (via the file which has all the .lstmf filenames) and creates intermediate .lstm files and _checkpoint files ------------------------------- these can be converted to the final .lstm file for use in traineddata -------------------------- the final .lstm file has to be combined using combine_tessdata to create new traineddata.
