Hi, I am trying to use V.VOL.RST to interpolate particle size for soil samples. i obtain the error message to increase DMin. unfortunately i have a data point every meter vertically and a total of 190K. if grass is asking to increase DMIN, which i have increased to 30 m to try to see if this was the pb, can I resolve this by reducing the Segment size?
