Whenever you don't know what's in your data (you think it contains whitespaces) print it to make sure.
use Data::Dumper;
local $Data::Dumper::Useqq = 1; # make "invisible" characters visible
print Dumper \@spliceout;

Then read about array interpolation in perldata:
Arrays and slices are interpolated into double-quoted strings by joining the elements with the delimiter specified in the $" variable

The problem is in this line:
  print MYFILE (">" . "$col_ID[$i]" , "@spliceout" , "\n");
