pyroms s_coordinate problems

[johan.navarro.padron]

Please Help!!!!...
I'm trying to make a grid with pyroms with the following values for vertical sigma coordinates.
hc = 5.0
theta_b = 0.4
theta_s = 5.0
Tcline = 3
N = 32
vgrd = pyroms.vgrid.s_coordinate(h, hc, theta_b, theta_s, Tcline, N)
But when it's finished the sigma levels are 3 instead 32.
Does anyone know what the problem is?

Greetings,
Johan
