.mlp files store MultiLoop models From the File menu, select open From the Open File dialogue, select a file
In this case, HalfPlanecoef1511.mlp is used

Step 2: Open a .mlp fileStep 2: Open a .mlp file
From the File Menu, Select open
Click “Open” when done
Select the file
Navigate to recent places and up the file tree here
Change the view to alternate between thehierarchy and sorted names here
Step 3: Model OpensStep 3: Model Opens
When the file is opened, the model is displayed
The mesh can be viewed in “mesh” or “tile” view
Keys “b”,”s” control the tile sizes Keys “l”,”r”,”u”,”d”,”i”,”o” control the view
Arrow keys control panning Go….

The mesh is shown as tiles. Tile colour variation indicates variable resistance
The line is drawn & annotated here in blue
Letters after theline labels referto the coordinate
Data are plottedin “stacked profile”format along theline

Step 4: Compute a responseStep 4: Compute a response
From the Calculate menu, select Response This starts the computation. A text output window records the progress of the calculation
Initially, the mesh is parsed. The resistive and inductive limits are found, then a time step solution in found
The profile response is then computed, and the data are plotted

A message box appears when the calculationis done. Click OK.
Step 7: Write out dataStep 7: Write out data
Data can be output to a Geosoft style ASCII file
Select the Exports Menu, then Write Data A file dialogue will appear, select the file to create
There is only simulated data in this session; you will be asked whether to write out transformed data.
Answer No, Transforms will be covered later

Select the file name to write
Select the directory
Save
Select yes to write the calculated data tothe file. Transforms will be explained later.Transforms allow the data to be transformedbefore writing.

An ASCII file with the data has been created.
This file can be opened with an a text editor such as TextEdit, BBEdit or WordPad
The file data can be imported into programs such as OasisMontaj and MultiLoop III
