Metric Results File

This document describes data that can be in the contents of the metric_results.csv file that is automatically created when GridMet is run.

mean_field_sizes

The mean of field sizes in pixels as a unit.

mean_field_sizes_px2cm

The mean of field sizes in centimeters as a unit.

mean_field_dists

The mean of field distances in pixels as a unit.

mean_field_dists_px2cm

The mean of field distances in centimeters as a unit.

minimum_angle

The minimum angle relative to the x- or y-axis of the most center field in the plot to its closest field.

matching_centroid_number

The centroid id number that is the closest field to the most center field. This field is used in the minimum_angle value reported.

grid_fields_reported

The number of grid fields that were detected and can be included in statistics. This value does not take into account any fields excluded from statistics with manual_field_exclud.

size_space_ratio

A ratio value of the mean size of fields vs. the spacing of fields.

in_out_ratio

A ratio value of the firing (or correlation) levels within fields compared to outside of them.

cov_mean

A value that is the mean of the coefficient of variation of the firing rates (or correlation values in the case of autocorrelograms) across fields.

gs_orientation

The orientation angle reported using opexebo’s methods.

gs_orientations_std

The standard deviation of orientation angles reported using opexebo’s methods.

field_1_x, etc.

These are x- and y-coordinates of each field’s centroid. This is reported when report_centroid_positions is enabled.
