SEPlib to m8r dictionary

SEPlib is a software package for seismic data processing developed at the Stanford Exploration Project. The dictionary below is intended for SEPlib users who are interested in either using Madagascar (m8r) or in finding out which algorithms/utilities are present in m8r, but not in SEPlib.

A m8r program, or a chain of m8r programs, will be considered equivalent to a SEPlib counterpart only if it has at least all the capabilities of its SEPlib counterpart. The fact that two of Claerbout's books (Basic Earth Imaging and Imaging Estimation by Example) and several SEP report articles have been reproduced with Madagascar shows that at least a significant subset of SEPlib is fully translatable. Individual programs may not be equivalent option-for-option. Like Lego blocks, they come together only when data flow examples are created from them, and such flows can certainly made fully equivalent even if the "building blocks" may differ slightly.

The starting point of the list below was the list of manual pages in SEPlib 6.5.3 (docs/man/man{1,3}/*.mn in the source code distribution). For programs, those files starting with a capital leter (the SEPlib convention for program names) were considered.

Programs

• 5dFFT
• Agc: sfagc
• AMO: sffkamo
• Aniso2d
• Attr3dhead: sfheaderattr
• Attr: sfattr

• CAM: sfcamig3
• Cfft: sffft3
• Contour: sfcontour
• Cp3d
• Cp: sfcp
• Create3d
• Cubeplot: sfgrey3: Cubeplot out=file.H >/dev/null is equivalent to sfgrey3 > file.rsf, and Cubeplot | Tube is equivalent to sfgrey3 | sfpen

• Edit

• Ftplot
• Fx2d
• Gauss
• Get: sfget
• Gfgradz
• Graph: sfgraph
• Grey: sfgrey: Grey out=file.H >/dev/null is equivalent to sfgrey > file.rsf, and Grey | Tube is equivalent to sfgrey | sfpen
• Grid_fold

• Headermath: sfheadermath
• Helicon: sfhelicon
• Histogram: sfhistogram
• Hwt3d: sfhwt3d

• Interleave: sfinterleave
• Interp
• Iso2d
• Kirch_2d_depth
• Kirmod3d: sfkirmod3
• Log
• Lpfilt: sfbandpass
• Marine_geom3d
• Math: sfmath
• MCvfit
• Median: sfmedian
• Merge: sfmerge
• Miss: sfmiss
• MTTmaps
• Mute3d
• Mute: sfmutter
• Mv3d
• Mv: sfmv
• Nmo3d
• Noise: sfnoise
• OFF2ANG: sfradon or sfslant, followed by sftan2ang.
• Operplot
• Overlay
• Pad: sfpad for padding with zeros, or sfspray for extending with the last value. Using sfspray directly will result in extending over an additional axis. To have an actual equivalent to Pad with extend option (extension across the same axis), sfspray can be used together with sfcat, i.e.: < inp.rsf sfwindow f2=-1 | sfspray axis=2 n=10 | sfcat axis=2 order=2,1 inp.rsf > out.rsf

• Ricksep
• Rm3d
• Rm: sfrm
• Scale: sfscale
• Scat3d
• Scat
• Sdd: sfdd, with option type= controlling the output (instead of esize=)
• Segy2sep: sfsegyread
• Seis_vel
• Sep2segy: sfsegywrite
• Sep2su: sfsuwrite, aka sfsegywrite su=y
• Smooth: sfsmooth
• Spectra: sfspectra
• Spike: sfspike
• SRM
• Stack3d
• Stolt: sfstolt
• Stretch: sfstretch
• Su2sep: sfsuread, aka sfsegyread su=y
