fixFlatFits: Fix Degenerate Stiffness Fits
In nstone8/Rasylum: Rasylum: AFM Data Analysis in R

Description Usage Arguments Details Value

Sometimes parExtractStiffness fits portions of the force curve before the probe is in contact (resulting in a stiffness of ~0). These functions attempts to find these degenerate cases and produce a better fit.

1 2	fixFlatFits(fits, minRise=.1,debug=FALSE, numCores=-1) forceNonFlatFits=function(fits,minRise=0.3,numCores=-1)

`fits`	Fit data produced using the function `parExtractStiffness`
`minRise`	The percentage of the total force range that the fit curve must traverse to not be considered degenerate.
`debug`	if `debug`==TRUE each fit will be plotted (the user should press 'enter' to cycle through fits) in order to allow for tuning of fit parameters.
`numCores`	Number of cores to use for the computation. If `numCores`==-1 all available cores will be used

If the fits being operated on by these functions cannot be fixed while honoring the other fit parameters set via parExtractStiffness fixFlatFits will leave the fit unchanged wheras forceNonFlatFits will increase the CPMaxF parameter until the minRise parameter can be satisfied.

A new object of the type produced by parExtractStiffness containing the updated fits
