Please answer by bottom-posting [1] to this mailing list to make it
easier to follow the conversation.

Those videos are rather old, created 2011.  I did not watch them in
detail, but I think there have been some improvements of how doing
things easier today (e.g. we have a GUI ;-) ).  Anyways, they might
serve as a good start as many commands did not change.

@Alexander Yelland: Regarding the Excel input, I think you should
familiarize with the Octave Forge IO package [2], especially the
`xlsread` function [3].  A very verbose explanation how to make it work
is given in the wiki [4].

Regarding the IDL scripts, do you mean [5]?  Three letter acronyms are
not unique in computer science ;-)  Please be precise.   At least I
don't know a tool to convert [5] to Octave scripts easily.  But it is
said that the syntax does not differ that much.
