Rounding values #35

Closed jh-guo closed 2 years ago

jh-guo commented 2 years ago

Hello, thanks for this amazing work! As shown in the figure, I was trying to get the IFT for my interfacial experiments and got the values rounded off automatically. I was just wondering how I can get IFT values accurate to two decimal places? Thanks! Image

Hello,

Thank you for the feedback. Unfortunately the number of decimal places displayed and saved is currently fixed. It was previously decided by rule of thumb that 3 sig. figs is probably sufficient, gauging the errors present in this sort of image analysis. However it looks like you're trying to compare IFT values across a series of photos, so as a workaround for now I've just hardcoded the app to show and save 4 s.f. instead (https://github.com/jdber1/opendrop/commit/6b3ca36eae3740645e8984b290bb896ee3a6cf5a).

You can get the updated version on the releases page: https://github.com/jdber1/opendrop/releases/tag/v3.3.1

In the future, we plan on adding some kind of standard error calculation for the estimated fit quantities (e.g. IFT, contact angle).
