File Management
Saving and Recalling Files
— Default – SNP data does NOT include smoothing. SNP data saves are taken 
AFTER data processing (location 2) on the processing chain.
— Advanced
 – SNP data includes the following:
— With Smith or Polar display format, SNP data saves are taken 
BEFORE most processing (location 1 on the data processing chain). 
— With any other display format, SNP data saves are taken just AFTER 
Formatting and Smoothing is applied (location 3 on the data 
processing chain). For each non-active trace, SNP trace data is 
reprocessed using the data processing chain of the active trace. 
See the FieldFox data processing chain at the Supplemental Online Help:
