Error Message: Input must be a row vector of characters.
Solution: This can happen when you pass a directory path into Imatest IT EXE with a trailing slash, and can be fixed by removing the slash:
May cause errors:
sfr.exe "-1" "C:\ImatestSamples\sfr_example.jpg" "C:\Program Files\Imatest\v4.5\IT\bin\" "C:\ImatestSamples\imatest-v2.ini" "C:\ImatestSamples\Results\"
Fixed:
sfr.exe "-1" "C:\ImatestSamples\sfr_example.jpg" "C:\Program Files\Imatest\v4.5\IT\bin" "C:\ImatestSamples\imatest-v2.ini" "C:\ImatestSamples\Results"
