Export powerpoint size is too small
From Array Suite Wiki
Array Studio View is too small in exported Powerpoint slides
When using Array Studio on computers with high-resolution "Retina Display" monitors, including when running a Windows Virtual Machine on Mac computers, exported Powerpoint images will only take 1/4th of the slide.
Computers with Retina Displays will often scale by "virtual pixels", such as drawing one displayed pixels on 2*2 actual monitor pixels. virtual machine software such as VMWare include an option to "Use full resolution for retina display". This option generally works well, but the virtual scaling is not properly translated to Microsoft Office export functions, so the exported Powerpoint image will be sized to 1/4 of the full slide.
If this occurs, you can either export a PNG, or turn off "Use full resolution for retina display" in VMWare, or the equivalent function in other virtual machine software.
