Input Data Options tomographic data (1) segmented data (2) burn data (3) medial axis data (4) throat data (5) pore-throat network data (6) fluid data (7) Enter choice: 4 Data Processing Options plot MA (1) plot MA with MS (2) convert MS files to segmented file type (3) histogram and fit pore MA burn data (4) embed search tree(s) (5) shortest paths (6) min cut/max flow (7) convert data to/from ascii format (8) convert MA list to/from node/path formats (9) modify MA (10) histogram MA info (11) throat calculation (12) convert to graph format (13) reconstruct burn layers (14) Enter choice: 6 Files assumed to be labelled basename.ext, basename is limited to 255 characters maximum, ext is a numerical designator lying between 000 and 999 It is assumed that the files have consecutively numbered extensions ie. 000 -> 056, or 021 -> 049 Enter basename for pma files: ../ma_t/sw Are files compressed? [y,n]: y Resize information selection. NOTE, row and column numbers begin from 0 For each slice, enter first and last column of data to use (x-dir): 0 255 enter first and last row of data to use (y-dir): 0 255 enter first and last slice of data to use (z-dir): 1 256 Do you want to trim the data? (y,n(dflt)): n Do you want 6 or 26 connectivity: 26 Dijkstra shortest path computations Labelling of cube faces /(6) (1)| / ___|____/__ / | /| 1st slice / | / | / / /| X /__________/ / | ------| | /------ (3) |_________|/ / (4) | | / | / | / |__/______|/ last slice / | Y / | (5) |(2) Z | Enter start face (1 -> 6): 3 Enter end face (1 -> 6, except 5): 4 By default all nodes on starting face are used in the Dijkstra calculation. If only a subrange of nodes are to be used, enter `r': Viewing options Print information on NBHD_LIST (l) Print Geomview data for viewing (g) Print jgraph data for viewing (2-D data only) (j) Print as medial axis data file (r) None of above (n) Enter choice? (l,g,v,j,r,n): g Request magnification of the view of the shortest paths in the Z direction? (y,n(dflt)): n Enter basename for writing absolute shortest path for geomview files: ../plots/tort_x_abs Enter basename for writing all shortest paths for geomview files: ../plots/tort_x_all Enter basename for face-to-face tortuosity distribution files: ../results/tort_x Enter data identifier for all histograms: berea sample, x-dir Set binning for tortuosity histogram number of bins (c) bin width (w) Enter choice: w Specify bin width to be used: 0.05
