I think the below will capture lines 2-6, but not line 1 (looks like 018328) is being captured by the regex. Is the syntax correct or is there a better way? Thank you .

I am trying to add a condition to the below perl that will capture the GTtag and place a specific string in the last field of each line. The problem is that the GT value used is not right after the tag rather it is a few fields away. The values should always be 0/1 or 1/2 and are in bold in the... (12 Replies)
In the tab-delimeted input file below I am trying to use awk to update the value in $2 if TYPE=ins in bold, by adding the value of
HRUN= in italics. In the below since in line 1 TYPE=ins the 117282541 value in $2 has 6 added because that is the value of HRUN=.

In the perl there is a default rule that sets f to VUS, and then a seris of rules that will change f based on the result that is
obtained from the rule. The code below is a rule that is supposed to be applicable to lines 2-4 because this rule just looks at the digit in f. So in line 2 f is 27... (4 Replies)

Hi,
So awk is driving me crazy on this one. I have searched everywhere and read man, docs and every related post Google can find and still no luck.

text::levenshtein
Levenshtein(3pm) User Contributed Perl Documentation Levenshtein(3pm)NAME
Text::Levenshtein - An implementation of the Levenshtein edit distance
SYNOPSIS
use Text::Levenshtein qw(distance);
print distance("foo","four");
# prints "2"
print fastdistance("foo","four");
# prints "2" faster
my @words=("four","foo","bar");
my @distances=distance("foo",@words);
print "@distances";
# prints "2 0 3"
DESCRIPTION
This module implements the Levenshtein edit distance. The Levenshtein edit distance is a measure of the degree of proximity between two
strings. This distance is the number of substitutions, deletions or insertions ("edits") needed to transform one string into the other one
(and vice versa). When two strings have distance 0, they are the same. A good point to start is: <http://www.merriampark.com/ld.htm>
"fastdistance" can be called with two scalars and is faster in most cases.
See also Text::LevenshteinXS on CPAN if you do not require a perl-only implementation. It is extremely faster in nearly all cases.
See also Text::WagnerFischer on CPAN for a configurable edit distance, i.e. for configurable costs (weights) for the edits.
