1) ShowPositions on the vector field, specifying every 10th, before passing to AutoGlyph 2) vectorfield->compute, giving the expression mag(a) 3) just pass the result of Compute to AutoGlyph

I am trying to plot glyphs of a vector field and I have several questions: 1) I keep running out of memory. I changed the type of glyph, which helped, but I would like to know how to plot only every tenth position or so. 2) I would like to use the compute module (or any module which works) to take the length of each vector in the field and output a scalar field. 3) If (2) can be accomplished, I would like to make the autoglyphs plot vectors based on magnitude. Thanks in advance, Kate White [EMAIL PROTECTED]
