open(DAT, "<$annotation_scheme_filepath") 1

open(DAT, "<$annotation_scheme_filepath")
|| die ("Cannot read file $annotation_scheme_filepath");

what does this line means?

i've been getting errors from this line

$annotation_scheme_filepath is a variable containing the name and extension of the file to open.

any obvious reason for the errors?

the program terminates here saying "Cannot read file $annotscheme at C:/Perl/site/lib/PP/PP_Engine.pm line155"

I already had the file annotscheme at C:/Perl/site/lib/PP.

 

[audiopro]

Cannot read file [red]$annotscheme[/red] at C:/Perl/site/lib/PP/PP_Engine.pm line155"

Is that the actual error you are getting because that var should be a file name and not a scalar?

no, that's my typing mistake

the errors should read

"Cannot read file annotscheme at C:/Perl/site/lib/PP/PP_Engine.pm line155"

 

[audiopro]

Cannot read file [red]annotscheme[/red] at C:/Perl/site/lib/PP/PP_Engine.pm line155

Again, that is not a file name should be at least a name and extension ie. myfile.txt

Do this:

open(DAT, "<$annotation_scheme_filepath")
|| die ("Cannot read file $annotation_scheme_filepath: [red]$![/red]");

$! will return the operating systems error message, like "file not found".

On Windows you don't need a file extension although that is the general case. The extension just lets Windows know which application to use to open a file. If there is no extension a dialog box pops up asking the user to pick an application. But in this case perl is opening the file so there is no problem with the lack of an extension.

Glad you got it sorted, sometimes you just need another pair of eyes to see it properly.
