The GeoStar software can also import sequence geometry from external sources. The point geometry, represented using any unit dimensions, can be stored in a text file and then easily imported into GeoStar via a two or three-point coordination method. This also works with sequence files created inside GeoStar, allowing users to return to samples and continue the analysis if the initial attempt was interrupted.
One useful application of external point importing is for loading point locations that have been analyzed by an electron microprobe. The XY coordinates from the microprobe can be stored in a text file and then imported into GeoStar, ensuring that the internal standard composition is correct for each ablation point.
