# Write GBCD Pole Figure (GMT 5)

## Group (Subgroup)

IO (Output)

## Description

This **Filter** creates a .dat file that can be used in conjunction with [GMT](http://gmt.soest.hawaii.edu/) to generate a grain boundary character distribution (GBCD) pole figure. The user must select the relevant phase for which to write the pole figure by entering the *phase index*.
