What I clearly don’t understand are the basic building blocks of Therion, folder structures etc</span></span></p></div></div></div></div></blockquote><span> </span><br>Nick, <br>the folders structure is not so important if you use correct .th file paths for input command.<br>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:<br><br>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:<br><br>scrap1@survey1.survey1+2.survey_big_passage.survey_big_system.survey_big_plateau.survey_big_mountains<br><br>Probably this could be more clear how therion is looking for data.<br><br>m.s.<br></div></div></body></html>
