Data processing as simple as 1 2 3 ....
Using the Labgrab© case sample wizard, shaping your sampled data to your
preferred specifications is as simple as 1 2 3 ...

- 2nd step: select your preferred type of sampling. You can
combine data of different files into one output file for each
processed case, or you can combine the same variable over different
cases into one output file. Select the extract interval (one output
sample per ... seconds), and the default way to sample.
|
 |
- 3rd step: select the variable(s) to process. For each variable, select
the preferred way of sampling. Variables from different input files
can be combined. For CaseCombineSample, a different output file
is created per variable. Each output file groups the sampled data for
a specific variable for all selected cases.

- ... last step: select the cases on which to apply the
processing.
- All cases will be processed as specified. Processing may take some
time, depending on the number of cases to be processed. For an average
of 45 cases to be processed, processing may require 5 to 15 minutes
on a PIII 850 with 256 MBytes of memory. Processing speed will heavily
benefit from added memory.
Keep in mind that processing requires reading all cases' files and
processing all data, and compare this to the time it would take you to
read all files in excel and to execute some manual way of subsampling....
