Sample1d - able to simply sample every nth value?

Q&A

Another silly question. Mine typically are!

Can sample1d ingest a file and “sample it,” without interpolation, reporting every nth value?

In other words, sample1d wouldn’t care about things being in time order, it would just be a simple down-sampling feature. Again, I’m applying this to a huge binary file, and not concerned (in this case) with data loss. Thanks!

You are setting yourself up for aliasing.
See gmt convert -Em

Appreciate the warning. Not computing any stats or anything of the sort. Its just to reduce the number of points being plotted. What I’m after will still be in the data.

I didn’t know about -Em in gmt convert. Very useful!
