# Different behaviour of List when imported from MX and CSV

On a sort of related question here, I noticed something odd about the behaviour of List.

When

Import["myCombinAnalysis.MX"]


was used, the List can be corrected used, but not when .CSV format was used. Both have the same Dimension and Head. And if you look at them by eye-inspection, they are the same data.

I found it very odd. What else could be different when they are sorted in MMA? How can I look/compare them?

• This is perhaps puzzling behavior at face value, but the CSV format saves data, whereas MX saves an expression. The difference might be subtle and difficult to track down. Really we cannot reliably say anything about what is going on without access to your actual files. Can you share them? How did you create the MX file? Could you include code as text rather than as (partly irrelevant) images? – MarcoB Jun 15 '18 at 14:17
