Re: [ferret_users] statistical significance, file reading

Hi -
Any expression inside grave accents must evaluate to a scalar.  Other 
than that, it's hard to answer a question like this. You need to give 
more details.

When developing a script, it is helpful to LIST individual parts of the 
expression you are trying.  That should allow you to see what the result 
of your definitions are and figure out what you need to do.

I made 3 files for this purpose, one the degrees of freedom (dof) for a region, second one is the t-values(tval) and the third one is the t-table with dimensions of significance levels(x) and degrees of freedom (y axis).  Now I want to find the significance levels from the third file based on the values in the first two files. I tried it this way,
