Thanks for the replies. What I clearly don’t understand are the basic building blocks of Therion, folder structures etc
Nick, the folders structure is not so important if you use correct .th file paths for input command. I use input xxx.th2 only on base level of surveys. If I need to use a scrap from a .th2 file I use the full addres of such scrap: to call from overall survey named "survey_of_big_country" where it is inputted file <big_mountains.th> with survey "survey_big_mountains" in it only "scrap1" from file <cave1.th2> inputted in file <cave1.th> in "survey1" I use such address: scrap1@survey1.survey1+2.survey_big_passage.survey_big_system.survey_big_plateau.survey_big_mountains Probably this could be more clear how therion is looking for data. m.s.
