gmtmath appears to be unable to compute quantiles in gmt5. Here is a simple example illustrating the bug.

gmt4% gmtmath -T0/100/1 T 99 PQUANT -Sl =
100.000000 99.000000

% gmtswitch gmt5
gmt5% gmtmath -T0/100/1 T 99 PQUANT -Sl =

It happens because info.T→n_records is never set ( == 0). I will fix this tomorrow.

Hello, I just installed the latest version of GMT on my Mac running El Capitan.

I get a similar error when trying to calculate PQUANT with a 95 setting.

Perhaps I don't have an environment set up properly? Everything else runs OK.

Hm, your command works for me but I am doing trunk. Will look at this later - at GSA Meeting so not much time for a few days.

Works fine for me too both in trunk and 5.3.3 so something else must be going on on your machine (likewise with grdmath issue)
