ANG_ROT | Array of three rotation angles (in degrees) used to improve the generation of the torque-variation pole confidence contours, since these can be inaccurate when the bulk of the torque-variation ensemble is close to any of the polar regions. The angles instruct MYRIAM to perform the three elemental rotations that seek to center and horizontally flatten the torque-variation ensemble on 0°N--0°E, where the contouring is more accurate. |
CTR_PATH | String path to a plain-text file containing the plate contour coordinates as two columns: [1] longitude and [2] latitude values, both expressed in degrees. |
DEF_DISTANCE_km | Value used to set a deformation buffer width (in kilometers) across the plate boundary. The boundary region has a linearly-decreased Euler vector magnitude, acting as a damped rigidity, as yielding an overall smaller torque-variation estimate. |
DIR_dM_PPD | |
DIR_MTX_w2M | |
DIR_OUTPUTS | Path to an existing directory in which all the output folders and files are stored. |
DIR_TMP | |
DM_CNTR_BINS | Array of values used to constrain the spatial statistical distribution of the torque-variation poles, and thus modify the resolution of the output pole confidence-contours: [1] resolution of the 2-D histogram grid in degrees, [2-3] minimum and maximum longitude of the grid, and [4-5] minimum and maximum latitude of the grid. |
DM_CNTR_PERCENT | Array of confidence levels (expressed as percentages) used by MYRIAM to calculate confidence contours of the torque-variation pole. |
DM_MAGHIST_BINS | Number of bins used to obtain the histogram showing the distribution of the torque-variation magnitude. |
EVo_PATH | Same as EVy_PATH, but for the older Euler vector. This input is optional, i.e., if omitted MYRIAM will assume that EVy_PATH already contains the difference between two Euler vectors at two particular stages. |
EVy_PATH | String path to a 3-column plain-text file containing an ensemble of sampled Cartesian values of the younger Euler vector, expressed in deg/Myr (degrees per million year). Alternatively, MYRIAM can sample its own ensemble from a singular Euler vector stage, by supplying a 10-column single line containing: [1-2] Euler pole longitude and latitude in degrees, [3] angular velocity magnitude in deg/Myr, [4-9] elements of the covariance matrix associated with the Euler vector ensemble, in rad²/Myr², and [10] size of the ensemble. |
FRACTION_HA | Value between 0 and 1 that sets the vertical fraction of the region utilized to define the depth-average viscosity of the asthenosphere using the model PM_v2_2012 by Priestley and McKenzie, 2013. |
GRID_RES | Value for the grid resolution of the plate's base, expressed in degrees. That is, the longitudinal/latitudinal spacing of the grid. |
HL_km | Value of the lithosphere thickness (i.e., depth of the lithosphere-asthenosphere boundary), expressed in kilometers. |
MATRIX_PATH | |
MODEL_LABEL | |
muA | Average value of the asthenosphere viscosity, expressed in Pa · s. |
muM | Average viscosity value of the lower part of the upper mantle, expressed in Pa · s. |
OUTPUT_LABEL | String that is added to all output directories and input report file to help the user setting apart iterations of the software without risking overwrite. |
OVERWRT_OUTPUT | Boolean that instructs MYRIAM whether to overwrite files. If false, MYRIAM will ask whether overwriting is desired, when encountering folders with the same name as the current intended output. |
PLT_LABEL | String that serves as plate label, and is added to all output directories and file names. It may also serve as plate identifier, which allow MYRIAM to use build--in plate contours from Matthews et al., 2016. |
PYTHON_PATH | String path to a Python3 executable in the running machine, used by MYRIAM to generate PNG figures. |
REGION_muA_LV | Rectangular geographic region for calculating lateral variations of the asthenosphere. If omitted, MYRIAM used the whole globe as region. If empty, a uniform asthenosphere viscosity is used as opposed to a laterally-varying one. |
RUN_LABEL | |
SAVE_ENS | Boolean that instructs MYRIAM whether to save or not the output torque-variation ensemble in a plain-text file. |
STG_IDX_1 | First integer element of STG_IDXs. |
STG_IDX_2 | Second integer element of STG_IDXs. |
STG_IDXs | Array of two integers, which serve as indexes to identify the two particular Euler-vector stages used. File labeling prevents overwriting, e.g., when using the same plate but different Euler vectors. |
