Thank you! I have not tried Larix yet but I will look into it. Miranda

I was able to fix the problem. Since I did not need the reordering of the standards, I changed the relevant lines of code back to the previous version. Here are the instructions I wrote myself to keep track of what I did: To fix Athena standards ordering issue: open this file: DemeterPerl>perl>site>lib>Demeter>LCF.pm (I opened in VSCode) Find: "foreach my $st (sort {$b cmp $a} @{ $self->standards }) {" Replace: "foreach my $st (@{ $self->standards }) {" Find: "my @stand = sort {$b cmp $a} keys %{ $self->options };" Replace: "my @stand = keys %{ $self->options };" Find: "my @stand = sort {$b cmp $a} keys %{ $self->options };" Replace: "my @stand = keys %{ $self->options };" open this file: DemeterPerl>perl>site>lib>Demeter>templates>analysis>ifeffit>lcf_report.tmpl (I opened in VSCode) Find: "{foreach $st (sort {$b cmp $a} @{ $S->standards }) {$OUT .= sprintf(". %-20s %.3f (%.3f) %.3f (%.3f)\n", $st->name, $S->weight($st), $S->e0($st)) }}" Replace: "{foreach $st (@{ $S->standards }) {$OUT .= sprintf(". %-20s %.3f (%.3f) %.3f (%.3f)\n", $st->name, $S->weight($st), $S->e0($st)) }}" open this file: DemeterPerl>perl>site>lib>Demeter>templates>analysis>ifeffit>lcf_save.tmpl (I opened in VSCode) Find: "$components = join(" ", grep {$_ =~ s{ +}{_}g; $_} sort {$b cmp $a} map {$_->name} (@{$S->standards}));" Replace: "$components = join(" ", grep {$_ =~ s{ +}{_}g; $_} map {$_->name} (@{$S->standards}));" Find: "@list = sort {$b cmp $a} map {$_->group} (@{$S->standards});" Replace: "@list = map {$_->group} (@{$S->standards});" Save file.
