Hi all,

I have been using the Demeter package for a year now and have recently been experiencing an issue when importing data. The following message pops up when importing data into Athena:

10:23:55: Argument "h_rmax = 4" isn't numeric in array or hash lookup at AppData/Roaming/DemeterPerl/perl/site/lib/Demeter/StrTypes.pm line 139.

Line 139 contains:

coerce Window, from Str, via { ($_ =~ m{[0-5]}) ? $window_list[$_] : $_ };

This usually pertains to line 139, but the following errors appear after the data import window is closed.  

10:23:58: Argument "h_rmax = 4" isn't numeric in array or hash lookup at AppData/Roaming/DemeterPerl/perl/site/lib/Demeter/StrTypes.pm line 139, <F> line 19.

The programme still runs; however, this pop-up is becoming slightly frustrating, given the amount of data I have. I have tried to use an older version, but the issue persists. This occurs with new and old data files, which were fine in the past. Do you have any ideas on how I can resolve this? I appreciate any help you can give me.
