Calories not displayed

[jakob jacobi]

I'm using SigmaRox 11.1 and GC 3.7.

Why the total calories are not displayed?

Thanks!

... ah... forgot to mention... and it's used with appimage on ubuntu.

You need, at least, to monitor heart rate for them to be computed

Likely because some data required to compute is not available, see https://github.com/GoldenCheetah/GoldenCheetah/wiki/UG_Special-Topics_Formula-Syntax-and-Expressions#metric-reference

thanks for fast reply.

but heartrate is monitored in that file too...

PS: since you have Work you can use it as an estimate of Calories,  if your cycling efficiency is around 23% it should be more accurate than estimates from HR.

Calories_(HR) - Total Calories estimated from Time Moving, Heart Rate, Weight, Sex and Age

All necessary data are collected or provided. In the profile on GC and also in the bike computer.

thanks. how can i do that? i can find only 'Calories' on the code.

You need Hear Rate in "Basic Data" tab, your screen capture is for "LAP" tab.

[jakob jacobi]

the screenshots before are from 'session' tab. heartrate is displayed in 'basic' tab too.

Here is the code: https://github.com/GoldenCheetah/GoldenCheetah/blob/cdcd47e4c19020ee5cf1ff1b9a3a861b8fc82aa7/src/Metrics/BasicRideMetrics.cpp#L3802-L3830, it needs Duration, Average Heart Rate, Age and Weight.

By use Work as an estimate for Calories I mean just interpret the kJ as kCal (yes, they are different units and measure different things, but when efficiency is around 23%, the factors cancel out).

BTW, one possible error source is age being negative, have you checked the century of your DOB?

[jakob jacobi]

yes, date of birth is correct with 1981.

in GC3.6 the calories were displayed as it was messured/calculated by the bike computer. used later a 3.6 snapshot coz some activity data from the rox11.1 were interpreted different in earlier version. since 3.7 the calories are displayed with 0. but in raw data the value is available...

This is weird since the code computing Calories from HR has not changed in the last 10 years... Lets do this: try to reproduce the issue in a minimum setup: create a new athlete, configure DOB and Sex and import that ride, if the problem still is there, take a backup and attach the zip file so I can debug.

 

but in raw data the value is available...

That is a different kind of animal... what you see in SESSION tab is the estimate from your bike computer, to use that value you have some options: manually override the GoldenCheetah metric with that value or learn how to create a User Metric using the XDATA function to retrieve that value automatically.

aaahh... i got it... you were right with DOB. when you go to the athlets input like DOB, height, weight etc the year of DOB is just displayed with last two digits and it was 81. when clicking on it, it shows 2081 instead of 1981. after edit that the calories are displayed in overview. maybe it's possible to change that to 4 digits instead of only two.

thanks for your help! :)

Users doesn't seem willing to check this even when directed to do so ...

  

thanks for your support and help! and also for providing such a tool like GC for all of us. but a little bit less arrogance would suit you better, sir... have a good one.

You are right, the generalization is incorrect, I should have written "some users", sorry...
