ps was my first try but I get "Invalid file format". Postscript is not
listed as supported file format (while eps is listed). I am not sure
what is the difference between eps level 2 and level 3 but here is what
'file' returns:
#> file test.*ps
test.eps: PostScript document text conforming at level 3.0 - type EPS
test.ps: PostScript document text conforming at level 3.0
I'm unable to import neither ps nor eps.
Thanks, Ted

That's why I converted the files to a format I was able to import. Actually that's one of my questions: Why I'm able to import eps level 2 but unable to import eps level 3 into Mathematica?
