In reverse order, the 10 most popular programs in Madagascar<\/tt> are:
\n10.<\/strong> sftransp<\/a> Transpose two axes in a dataset (used in 83 projects<\/em>)
\n9.<\/strong> sfadd<\/a> Add, multiply, or divide RSF datasets (used in 92 projects<\/em>)
\n8.<\/strong> sfgraph<\/a> Graph plot (used in 99 projects<\/em>)
\n7.<\/strong> sfspike<\/a> Generate simple data: spikes, boxes, planes, constants (used in 109 projects<\/em>)
\n6.<\/strong> sfcat<\/a> Concatenate datasets (used in 110 projects<\/em>)
\n5.<\/strong> sfput<\/a> Input parameters into a header (used in 118 projects<\/em>)
\n4.<\/strong> sfmath<\/a> Mathematical operations on data files (used in 143 projects<\/em>)
\n3.<\/strong> sfdd<\/a> Convert between different formats (used in 163 projects<\/em>)
\n2.<\/strong> sfwindow<\/a> Window a portion of a dataset (used in 216 projects<\/em>)
\n1.<\/strong> sfgrey<\/a> Generate raster plot (used in 260 projects<\/em>)
\nMore documentation on these and other programs – in Guide to Madagascar programs<\/a>.
\nThe three most popular programs in the “generic” category (signal processing programs applicable to any kind of data) are sffft1<\/a> (Fast Fourier Transform along the first axis), sfnoise<\/a> (Add random noise to the data), and sfsmooth<\/a> (Multi-dimensional triangle smoothing).
\nThe three most popular programs in the “seismic” category (signal processing programs applicable to seismic data) are sfmutter<\/a> (Muting), sfricker1<\/a> (Convolution with a Ricker wavelet), and sfsegyread<\/a> (Convert a SEG-Y or SU dataset to RSF).
