gpdcmisfit
Recomputation of misfit. Did you generate a collection of models that you want to use as the starting population for slightly different dispersion curve? No problem, correct misfits and import it.

gpdcreport
Query tool for binary inversion report produced by dinverdc. With option '-pm' this tool is also usefull for all report types produced by dinver (e.g. dinvermatlab, dinverext or any custom inversion plugin).

gpec8

gpell
Computation of theoretical ellipticity curves.

gpgroup2phase
Convert group velocity dispersion curves to phase velocity. Hmm! The solution is not unique. Ok this tool scans for various possibilities.

gpmodel2param
Transforms a 1D wave model into a ground parameterization that you can import inside Dinver (dinverdc plugin).

gpparam2model
Generate 1D wave models given a parameter set and a parameterization definition.

gppoisson
A memo for Poisson's ratio formula. Quick transform from Vp, Vs to nu and vice-versa.

gpprofile
Transform a 1D wave model into a plotable curve. Can also compute a variety of useful profiles from 1D wave models: impedance, Poisson's ration, travel time average (Vs30 or VsZ).

gprefra
Computation of theoretical refraction travel times (1D model or tilted model).

gpsh
Computation of theoretical SH transfer function for a 1D wave model (Hmm! still to finish its implementation).

gpsignal
Computation of custom cosine signals. Stacks of multiple frequencies and phases. Support for phase shifts between various station locations.

gpsort
Sort curves stored in a text file (one after the other, various columns for X, Y,...). Usefull to re-order curves produced by gpspac and pipe them to figue in the correct order (play with option '-cpp').

gpspac
Computation of theoretical autocorrelation curves.

gpviewdcreport
Ploting tool for report files produced by dinverdc plugin. Provides the same output as inside Dinver graphical interface for automatic bash scripts.
