Hi Gquadro,

Maybe because PtByPt-DataQueue expects scalar values?!

When you already have your data as a 1D array then you could use a loop (without autoindexing) and ArraySubset to read subsets of 60 elements: basic array handling as taught in the Training resources. Did I mention the Training resources before?

Could you help me with this part? 

There is a ptbypt version of array min&max, so use that. Note that the first slope is NaN (because we only have 1 value!), so you need to initalize on the second iteration. Also note that you might want to ignore the first results, because they don't rely on a full set of values, so initialize min&max if e.g. i=59 or similar.

This will give you the slope, not the "angle", so add a little trigonometry. I trust you can do that.

Then I would like to write these values (max and min) in an external file.

There are millions of ways to write two values to a file. What have you tried?
