Hi,

I'm pretty sure I'm losing saved data at random times (e.g. the "disappearing data" problem), even though I'm on 16.0.2. I just spent a few hours re-creating some variables from 3 days ago. Not pretty - I'm almost to the point of learning R and doing something destructive with my SPSS CD (not that it would help, but it might feel good for a short while :)

But - in the interest of making sure that my problems are not my own doing...

I work with some fairly large datasets that evolve over time through ongoing data collection. Periodically I download new files, re- calculate variables, and save iterations of versions (in addition to interim saves due to the "disappearing data" issue). I'm trying to think of practices I can use to make sure I'm working with the most recent version of everything. I do keep variable definitions and analysis syntax in syntax files (including relevant filters, selection commands, etc.), so I can reproduce analyses when needed.

If you have any SPSS "best practices" you'd be willing to share I'd love to hear them. I'm concerned that it's all too easy to make all sorts of silly mistakes in SPSS -

Thanks, --Linda
