I'm confused. You seem to have taken a step back (the latest error is
saying that the input file doesn't exist). You started with this:

*$ pandoc GENIe_scripting_reference.md -o GENIe_scripting_reference.pdf*
*YAML parse exception at line 9, column 9: mapping values are not allowed
in this context*

Starting with the downloaded file, this worked for me:


*$ perl -pe 's/^---$/---\n/igs' GENIe_scripting_reference.md
>GENIe_scripting_reference.fixed.md
<http://GENIe_scripting_reference.fixed.md>$ pandoc
GENIe_scripting_reference.fixed.md
<http://GENIe_scripting_reference.fixed.md> -o
GENIe_scripting_reference.pdf*

Note that Albert's suggestion (i.e., ensure that "---" lines are always
followed by a blank line) is much better than mine. My suggestion caused
problems with unintentional tables (due, I suppose, to "- - -" lines not
being followed by blank lines).
