I am trying to use the Slab program to generate meaningful ground temperature values. I am using the sample IDF file shown in the "AuxililaryPrograms" document (with few modifications to suit my needs) and I run into two problems.
First, when I try to open the IDF in the EP Launch, it shows an "Invalid Slash Codes Found" window. The message says:
\obsolete=>EquivalentSlab
\obsolete=>EquivalentSlab

It also crashes when I run using the Phoenix,AZ epw file
My IDF is this:
