Properties

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.
