Splitxyz not working as expected

Q&A
1

Hi all, I’m trying to split my trackline data into line segments using splitxyz. Below is the command I’m using

gmt splitxyz sample.txt  -fg -C45 -Vl > split.txt

sample.txt has: lon lat and depth values

Attached is the image of the track plot. splitxyz is only splitting the data into 5 segments, but the data contains about 30 segments. Can you please let me know where I’m doing it wrong. Thanks.
