Why won't Prism import all my data?

Prism versions 2 and 3 are limited to 52 data sets per table, and the capacity of each data set is 10,000 values divided by the number of replicates. Thus, if you format the table for single Y values, then you can import 10,000 values into that data set. If you format the data set for entry of triplicates (or entry of mean, SD and N) then you are limited to a bit more than 3000 points. If your data file has more data than that, Prism simply stops importing when its tables are full.

In some cases Prism 3.00 will stop importing before the table is full. This is because it uses the column format of the default table, not the table you are using now, to decide how many rows to import. To work around this problem, set the default format to a single column of values. To do this, click Change from your table, choose Column Format and select "single column of values". Then check the option to "make these choices defaults". We fixed this problem in releases 3.02 and 3.03.

Prism 4 can have tables with up to 104 data sets, each with up to 52 replicates. The number of rows is limited only by your RAM and hard drive.
