psvelo can't get error ellipse #992

Closed Soengmou closed 5 years ago

Soengmou commented 5 years ago

I just install the GMT in the Ubuntu 18 online to plot a GPS rate field with the command below I used in under the CentOS. But don't get the error ellipse. ”echo 80 30 10 0 2 2 0 10mm/a| gmt psvelo -h0 -R -W0.8,black -Gblack -J -L -Se0.04c/5/10 -A0.19c+p0.7p+e -O -K -V >>$psn”

I just copy one line of my script.

seisman commented 5 years ago

I don't know the exact meanings of the arguments, but it seems the second argument of -Se is confidence, which should be in the range of 0-1. Please see the psvelo manual for detailed description.

Changing -Se0.04c/5/10 to -Se0.04c/0.5/10, and you'll see an ellipse. Maybe that's what you want.

Soengmou commented 5 years ago

Sorry for the argument. But you got my meaning. I changed the confidence to 0.5. It doesn't work. My GMT version is 5.4.3.

seisman commented 5 years ago

I tried the following command with GMT 5.4.5:

echo 80 30 10 0 2 2 0 10mm/a| gmt psvelo -h0 -Rg -W0.8,black -Gblack -JH10c -L -Se0.04c/0.8/10 -A0.19c+p0.7p+e -N -V -Baf > map2.ps

This is what I got: image

Soengmou commented 5 years ago

Thank you. The error ellipse was displayed when I added the -B .

seisman commented 5 years ago

That's weird. -B isn't required here. This is what I got without -B. image

Does your script properly end the postscript or is there a final -K hanging?

There's no -K hanging in the last line.

Yeah, very wired.

PaulWessel commented 5 years ago

Since it seems to work fine in 5.4.5 there isn’t anything we can do as long as Ubuntu is so far behind on releases. You would need to build from source.
