Main Administrative Menu – Edit

The edit menu contains many useful tools for data cleansing and hygiene.

Edit > Add Torque Values

Derive torque when power and cadence data is available. This chart can then be added to the activity submenu using the top right Hamburger Menu > Add Charts > histogram

Change the Data Series to Torque and click on OK to add this to the Scope bar (C)

Edit > Adjust Power Values

Lets you to uplift or degrade the power values by a percentage and/or a fixed value. It takes two parameters:

  • Percent Adjustment: This defines percentage to modify values by. Negative values are supported.
  • Fix Adjustment: This defines a fixed value to modify values by. Negative values are supported.

If both parameters are given, first the relative adjustment takes place, and then the fix value adjustment is applied on the result.

Edit > Adjust Torque Values

Adjusting torque values lets you to uplift or degrade the torque values when the calibration of your power meter was incorrect. It takes a single parameter:

  • Torque Adjust: This defines an absolute value in pounds per square inch or Newton meters to modify values by. Negative values are supported. (e.g. enter “1.2 nm” or “-0.5 pi”).

Edit > Estimate Distance Values

Derive distance based on GPS position.

Some devices don’t record distance but do record position (eg Timex Cycle Trainer).

Edit > Estimate Headwind Values

Use weather broadcast-ed data in FIT file to derive Headwind.

Edit > Estimate Power Values

Derive estimated power data based on speed/elevation/weight etc.

The Bike Weight parameter is added to the athlete’s weight (as entered in Tools > Athletes > Options > Athlete > Measurement to calculate total mass, Bike weight should include apparel, shoes, etc.

CRR parameter: This is the coefficient of rolling resistance, leave as default or enter the value if you know it.

Coefficient of rolling resistance of common tyres can be found here

CdA parameter: This is the effective frontal area in m^2, it depends on position and equipment. If 0 then the value is estimated from anthropometric data

Draft Mult. parameter: This is the multiplier to adjust for drafting, 1 is no drafting  and 0.7 seems legit for drafting in a group

Wind (kph) parameter:  This is the wind speed in kilometres per hour.

Heading parameter: This is the wind direction (origin – the direction the wind is coming from). The unit is degrees from -179 to +180 (-90=W, 0=N, 90=E, 180=S).

Note:  Data field is labelled heading. This is incorrect you should enter the direction value here.

Note: If the ride file already contain wind data this will be overridden if wind is entered manually here.

Edit > Estimate Running Power

Derive estimated running power data based on speed/elevation/weight etc using di Prampero coefficients.

Equipment Weight parameter is added to athlete’s weight to compound total mass, it should include apparel, shoes, etc.

Draft Mult. parameter is the multiplier to adjust for drafting, 1 is no drafting  and 0.7 seems legit for drafting in a group.

Wind speed is in kph.

Wind direction (origin) unit is degrees from -179 to +180 (-90=W, 0=N, 90=E, 180=S).

Note: if the activity file already contains wind data this will be overridden if wind is entered manually here.

Edit > Filter R-R Outliers

Lets you to remove RR outliers to improve HRV accuracy

Edit > Fix Elevation errors

Fix or add elevation data. If elevation data already exists it will be removed and overwritten.

NOTE: AN INTERNET CONNECTION IS REQUIRED TO USE THIS.

Edit > Fix freewheeling power/cadence

ANT+ crank based power meters will send 3 duplicate values for power and cadence when the rider starts to freewheel. The duplicates should not be retained. This tool removes the duplicates.

Edit > Fix GPS errors

Remove GPS errors and interpolate positional data where the GPS device did not record any data, or the data that was recorded is invalid.

Edit > Fix Gaps in Recording

Many devices, especially wireless devices, will drop connections to the bike computer. This leads to lost samples in the resulting data, or so-called drops in recording.

In order to calculate peak powers and averages, it is very helpful to remove these gaps, and either smooth the data where it is missing or just replace with zero value samples

This function performs this task, taking two parameters:

  • Tolerance: This defines the minimum size of a recording gap (in seconds) that will be processed. Any gap shorter than this will not be affected.
  • Stop: This defines the maximum size of gap (in seconds) that will have a smoothing algorithm applied. Where a gap is shorter than this value it will be filled with values interpolated from the values recorded before and after the gap. If it is longer than this value, it will be filled with zero values.

Edit > Fix HR Spikes

Occasionally heart rate sensors will erroneously report high values for heart rate or drop out (0). This function will look for spikes and dropouts in heart rate data and replace the erroneous data by interpolating the data from either side of the point in question

It takes the following parameter:

  • Absolute Max: This defines an absolute value for heart rates, and will smooth any values above this absolute value that have been identified as being anomalies (i.e. at odds with the data surrounding it).

Edit > Fix lap swim from length data

Sometimes length times or distances from lap swimming files are wrong.

You can fix length-by-length information in Editor SWIM tab: TYPE, DURATION and STROKES.

This tool recalculates accumulated time, distance and sample Speed/Cadence from the updated lengths.

Laps are recreated using pause lengths as markers

Pool Length (in meters): Lets you re-define the field if value is > 0

Edit > Set sm02/tHb from Speed and Cadence

When recording from the Moxy or BSX Insight in speed and cadence mode the SmO2 and tHb data is sent as cadence and speed respectively. This tool will update the activity file to move the values from speed and cadence into the Moxy series.

Edit > Fix Power Spikes

Occasionally power meters will erroneously report high values for power. For crank based power meters such as SRM and Quarq this is caused by an erroneous cadence reading as a result of triggering a reed switch whilst pushing off.

This function will look for spikes/anomalies in power data and replace the erroneous data by smoothing/interpolating the data from either side of the point in question

It takes the following parameters:

  • Absolute Max: This defines an absolute value for watts, and will smooth any values above this absolute value that have been identified as being anomalies (i.e. at odds with the data surrounding it).
  • Variance (%): This will smooth any values which are higher than this percentage of the rolling average wattage for the 30 seconds leading up to the spike.

Edit > Fix Running Cadence

Some files report cadence in steps per minutes. This tool converts this to revolutions or cycles per minute

Edit > Fix sm02 and/or tHb anomaly

Occasionally SmO2 (%) and/or tHb (%) will erroneously report missing or high values (SmO2: 0% or >100% / tHb: 0% or > max. tHb parameter).

This function will look for those anomalies in SmO2 and tHb data and, depending on the configuration, replace the erroneous data by smoothing/interpolating the data from either side of the 3 points in question. It takes the following parameters:

  • Fix SmO2: Check to fix anomalies in SmO2 data.
  • Fix tHb: Check to fix anomalies in tHb data.
  • tHb: Any tHb above is considered an outlier.

Edit > Fix Speed and Distance

Some devices report sample speed not matching the change of distance, for example when using a footpod for speed and GPS for distance.

This tool replaces the existing speed channel, or creates a new one if not present, based on travelled distance. It takes a single parameter:

  • Moving Average Seconds: This parameter lets you to set the seconds of the MA filter to smooth speed spikes.

Edit > Set xData.CDA from HR

When recording with an iBike AeroPod (in HR mode) the CdA data is sent as HR. This tool will update the activity file to move the values from HR into the XData.CdA series.

Edit > Snippet export

Dump metrics for the ride to Athlete_Home/Snippets.
