Hi Jean-Marie,

Look at the compressi function.

Here is an example:

yes? use levitus_climatology

List a vector
yes? list temp[i=23,k=1]

Remap on a choosen axis
yes? let vector1=xsequence(temp[i=23,k=1])
yes? list vector1

Compress vector
yes? let vector2=compressi(vector)
yes? list vector2

Find number of good point
yes? list vector2[i=@ngd]

Define a new variable with only unmaked values
yes? def sym maxindexvector=`vector[i=@ngd]`
yes? let vector3=vector2[i=1:($maxindexvector)]
yes? list vector3
