Thanks, Xavier! This has worked. Any idea what Therion's "default grade" is if I do not specify anything?

Assuming grade 5, the statement would be: data normal from to length compass clino ignoreall grade BCRA5 ## Stddev of normal legs WGB26 WGB27 20.5 30 0 # This leg below has perfect measurements sd length 0 meter sd compass 0 degrees sd clino 0 degrees WGB27 WGB28 17.1 95 0 grade BCRA5 ## Back to the stddev of normal legs WGB28 WGB29 9.5 120 0 If this does not work, try 0.0001 instead of zero as I remember having problems with vanishing stddevs. Xavier Le 15-Jun-18 à 13:29, Michael via Therion a écrit : > Hello Ben, > Thanks for the hint to use "SD" but I need some more help with that. > > For example, I want *only* leg from WGB27 to WGB28 to exclude from > modification by Therion's loop closure algorithms. > What statements do I need to insert at what places to ensure that? > > data normal from to length compass clino ignoreall > > WGB26 WGB27 20.5 30 0 > WGB27 WGB28 17.1 95 0 > WGB28 WGB29 9.5 120 0 > > Michael. > > _______________________________________________ > Therion mailing list > [email protected] > https://mailman.speleo.sk/listinfo/therion -- > ------------------------- > Xavier Pennec > Senior Research Scientist / Directeur de recherche Asclepios > project-team, INRIA Sophia-Antipolis > 2004 Route des Lucioles, BP93 > F-06902 Sophia-Antipolis Cedex, France > +33 4 92 38 76 64 > +33 6 78 35 16 90 > http://www-sop.inria.fr/asclepios/ > ------------------------------- _______________________________________________ Therion mailing list [email protected] https://mailman.speleo.sk/listinfo/therion _______________________________________________ Therion mailing list [email protected] https://mailman.speleo.sk/listinfo/therion
