• Home Page: https://github.com/MTgeophysics/mtpy
• Issue tracking: https://github.com/MTgeophysics/mtpy/issues

Note that this repository has superseded the geophysics/mtpy and GeoscienceAustralia/mtpy2

• Python 2.7.*
• Python 3 (Todo)

1. Install Python environment and dependency packages. See Wiki Pages: https://github.com/MTgeophysics/mtpy/wiki
2. Obtain the source code from https://github.com/MTgeophysics/mtpy:

• git clone https://github.com/MTgeophysics/mtpy.git

• cd mtpy

  - pip install -v --user -e . (into user's own home ~/.local/lib/python2.7/site-packages/mtpy.egg-link) OR

  - python setup.py develop --user OR

  - pip install -v -e . (into python lib's dir site-packages, write-permission required) OR

  • export PYTHONPATH=/Path2/mtpy:$PYTHONPATH (Only valid for each session)

To verify the install:

• pip list | grep mtpy

To uninstall the mtpy package:

• pip uninstall -v mtpy

MTpy is licensed under the GPL version 3

The license agreement is contained in the repository and should be kept together with the code.

1. MTpy uses E- and B-fields (although the sensors may be confusingly named as H-sensors in EDI files)
2. [E] = microvolts/meter (muV/m)
3. [B] = nanotesla (nT)
4. [Z] = [E]/[B] = km/s
5. Apparent resistivty rho = 0.2 * T * ^2 (in Ohm m)
6. Angles are given in degrees (mod 360)
7. EDI files can contain data in Z- or rho/phi-form
8. EDI files contain data from one station only
9. Coordinates are handled in decimal degrees (converted when reading)
10. Time stamps refer to UTC
11. Internal coordinates: X = North-South, Y = East-West
12. Rotations are interpreted clockwise (mathematically negative)
13. 0 degrees azimuth = North
