Hey thanks a lot for your reply. This seems to be a great idea to use hin data with sanskrit wordlist.
Still I am interested in knowing the things building from scratch. So I used some boxfiles and images I created for sanskrit 2003 font and used the hindi config file from https://github.com/tesseract-ocr/langdata/blob/master/hin/hin.config and I renamed it as san3ds.config. san3ds(3 for 2003 ds for devanagari split) is the new name I am giving for my new training data. I was able to train san3ds without any config file before. I just renamed san3ds.word-dawg as san3ds.cube-word-dawg. Remaining files I kept as it is. I could form san3.traineddata file, but I am getting an error while recognition:- Cube ERROR (CubeRecoContext::Load): unable to read cube language model params from /usr/local/share/tessdata/san3ds.cube.lm Cube ERROR (CubeRecoContext::Create): unable to init CubeRecoContext object init_cube_objects(true, &tessdata_manager):Error:Assert failed:in file tessedit.cpp, line 214 Segmentation fault (core dumped) Any help in this, why this is happening? Is it wrong in renaming word-dawg, I cannot find any separate option for generating cube-word-dawg.
