Analyst TEM inversion using geoapps: Type error

[craigmillernz]

When trying to run a TEM (skytem) inversion directly in Analyst using geoapps (on Windows) I get this type error. It appears to be an issue with alpha_x. I've tried setting this to 1.0 (instead or just 1), but makes no difference.

Update: there appears to be no alpha_x written to the ui.json - see attached

White_island_TEM_model1.ui.json

JIRA issue [GEOPY-1227] was created.

Can you provide your ui.json?

[craigmillernz]

attached to the original post. it looks like alpha_x isn't written to ui.json, only alpha_s

[domfournier]

Right, so we are now using length_scales under the hood. So I suspect that your geoapps may not be on 0.11.0?

[craigmillernz]

ok correct, i'm using the version that comes default with analyst 4.2.1 which is 0.10 i think

[craigmillernz]

is 0.11 officially out yet?

[domfournier]

Still a release candidate. If you install GA 4.3, it will come with it.

[domfournier]

Are we good with this @craigmillernz, back online?

[craigmillernz]

yes my mistake on this one, all good to close

[domfournier]

Great thanks.
