We received a question from Ilan Shrira, who got an error while saving a file:
I just bought a 120 gigabyte external hard drive, and whenever I try to save an SPSS file
that’s more than 4 gigabyte onto it, it stops and says “Warning #5322, The attempt to save the data file has failed because the disk is full, an I/O error has occurred, the variable dictionary is invalid, or the task was interrupted”
I didn’t have any trouble saving 2 or 3 gigabyte files of the save type. Is is possible that there’s some other kind of glitch in my file.”
This is a preview of Error: The attempt to save the data file has failed because the disk is full, an I/O error has occurred, the variable dictionary is invalid, or the task was interrupted.

We get a lot of questions about regression analysis. We have dug into this and decided to write a post about it, so we can help everyone with this.
You do a regression when you assume that a variable is influencing another one, like in the following example: We assume that cars that run on Diesel have higher costs.
To test this assumption, we run a Linear Regression in SPSS. Take the following steps:
- Define your dependent and independent variable. In our example Fuel is the indepent variable and Costs is the dependent one.
- Click Analyze
- Go to Regression and click Linear
- Click “Fuel” into the Independent variable field, and “Costs” into the Dependent variable field.

This week we got a question from Timo.
Is it possible to use syntax when recoding variables? For example, if I
had a variable that included the following values:
Ladybird
Bluebird
Elm
Butterfly
and I wanted to recode any values that included ‘bird’ into a new value
‘bird’, can I do this with the Recode transformation?
To solve to problem the following syntax is an option:
DATA LIST LIST /var1(A15).
BEGIN DATA
Bluebird
Ladybird
Birdwatcher
Butterfly
Elm
END DATA.
STRING newVar(A15).
DO IF INDEX(UPCASE(var1),”BIRD”) > 0 .
- COMPUTE newVar=”BIRD”.
END IF.
EXECUTE.
