Here some Matlab routines (m-files) are stored. These Matlab programs can be used to find optimal relaxation frequencies to approximate a constant Q (qapprox.m) or to plot Q as a function of frequency for certain relaxation frequencies and value of tau (qplot.m). It is necessary to have the Matlab Optimization Toolbox installed. For further details on the theory behind these algorithms we refer to the Phd thesis of T. Bohlen\cite{bohlen:98} and to the paper in which the so-called tau-method is described \cite{blanch:95}. The parameter tau is used in this software to define the level of attenuation.

The wavefield snapshots can be merged using the program \textit{snapmerge}. The program snapmerge is not a MPI program. Therefore, it can be executed without MPI and the mpirun command. You can run snapmerge on any PC since a MPI environment (e.g. LAM) is not required. You may therefore copy the snapshot outputs of the different nodes to another non-MPI computer to merge the files together. \textit{snapmerge} reads the required information from the DENISE parameter file.
