Importing a .mpjx file



I am currently taking a course that requires Minitab which appears to be unavailable for Linux systems. After doing some searching, I was read that RStudio can run Minitab files and to import it using the following steps:

myMTPData <- read.mtp("orientationdata.mpjx")

This leads me to the following error:

Error in read.mtp("orientationdata.mpjx") : 
  file 'orientationdata.mpjx' is not in Minitab Portable Worksheet format

Is there any way to determine this or is there any way to import .mpjx files that are not in a Minitab Portable Worksheet?

Thank you for your time.
