Thanks. I guess I'll have to try another approach. I changed the sample length to 2 (I didn't read the documentation very carefully, I thought the sample length was in bits, not bytes) and now it works, but I'm left with an array of floating point numbers, and I still have the problem of writing it out again.
I'm still getting a warning message, but I'm not sure what it's trying to tell me: warning: array array1: clearing save-in-patch flag David.
