Incorrect file in lab testing tutorial

I'm trying to work through the tutorial for gIINT lab testing. The zip folder I downloaded does not appear to have the required Excel file. The included file is named corresp_file_test_data.xls. According to the tutorial, the file should be training_lab_test_data.xls. Can someone help? 

Also, I was tasked to supply grain size distributions in gINT format. Can someone clarify what that format is? Does this imply a particular data structure in Excel that allows for the data to be imported into gINT? 

Can I generate sieve lab reports based on surface grab samples that are not associated with any borings?

Thanks in advance,

Anthony
