Hi, Reema.

You can specify a destdir in the getGEO command.  All files will be
downloaded to that directory.  If there is a file of the appropriate name in
that directory, the getGEO command will use that file before downloading.
 In other words, GEOquery tries to cache files in the destdir directory.  If
you were to replace the GPL file with one of the same name and it is a valid
file, then GEOquery will pick that up instead of downloading.

Just out of curiosity, where did the other soft file come from?  I do not
know of other software or vendors that are using the SOFT format.

You cannot specify the path to the SOFT file directly.  However, as I
mentioned, you can save the file in the destdir directory and it should be
used.  Alternatively, you can always simply replace the featureData from the
ExpressionSet with featureData of your choosing, including that obtained
from a separate call to getGEO where you specify the path to the GPL file
you have stored locally.

Again, I'm not sure what the use case is here, so please clarify if what I
describe is not what you need.
