# Saving the residuals with the data

## !RESIDUALS

!RESIDUALS [ `n `]

instructs ASReml to write the transformed
data and the residuals to a binary file. The residual is the last
field. The file
`basename`.srs
is written in single precision unless the argument is 2
in which case
`basename`.drs
is written in double precision.
The file will not be written
from a spatial analysis (two-dimensional error) when the data records
have been sorted into field order because the residuals are not in
the same order that the data is stored.
The residual from a spatial analysis will have the units
part added to it when units is also fitted. The
.drs file could be renamed
(with extension .dbl) and used for input in a subsequent run.
