Reason: Add CODE tags, remove extraneous closing COLOR tag. Removed spurious space and a newline from first sample file
Maybe because FS is set to '\t' and there appear to be no TABs in your second sample file, so the fields will not match. And you are setting the index to the entire record, save the first character. which is probably not what you want (you probably meant to use $1 here, but that would not be a sure way to do it either, because in the FASTA format the identifier is allowed to contain spaces). And the FASTA file is word wrapped, so you need to take out the newlines and not use getline to get only the second line ....
The best way to do that is is to use ">" as a record separator and use "\n" as the field separator. By setting OFS as the empty string, and assigning a value to one of the fields, all newlines will be replaced by empty strings, so this will effectively remove the word wrap. And the sequence will become one continuous string, which will make it suitable for substring selection.
Using your file order, we would get something like this.
With your two sample input files (with the combined lengths of the lines in each group that do not start with a > being less than 100 characters), I don't see how you would expect any output when the substring you are trying to extract from those strings starts more than 40,000 characters into that string, and in two of the three cases has an ending position in the string that comes before the starting position (thereby requesting a substring that has negative length).
In addition to those problems, as Scrutinizer said, your script specifies that the input field separator for file2 is a tab character, but there are no tab characters in the data you showed us. Therefore, you are requesting a substring of 1 character starting at position 0 (when arrays of characters in awk start at position 1).
Note also that although you might be able to create an array element in awk or gawk on Ubuntu that is more than 323,000 characters long; on most UNIX systems and BSD-based systems, awk won't let you read a line, write a single output string, or create a variable whose value is much more that LINE_MAX bytes long (on most systems LINE_MAX is 2,048).
This User Gave Thanks to Don Cragun For This Post:
and we want a awk script which creates an output file which contain sequences extracted from these coordinates along with id with > symbol .
for example:
The comments by Don Cragun still apply: most of the sequences are shorter than the coordinates that you have in your file2, and there are coordinates that result in negative string lengths.
On top, none of the samples in file2 match any of those in file1.
from the file result.ods which I thought meant that you wanted characters 52962 through 52984 from the data following a line starting with:
Code:
>gi|546709146|gb|AWWX01426952.1|
in the file 1.fasta. But, that string does not appear in 1.fasta and, even if it did, the data from characters 52962 through 52984 would be 23 characters long; not the 138 characters you have said you want to have output.
may be that entries would be at the bottom of the file actually sir, i just copied and posted very few entries from file1 and file2 may be matched would be skipped. i cant paste my whole data file here i have 4565005 sequence entries in my data.
and about negative value, please provide me the script for like 300 250 = 50
no problem if there is 250-300 =-50 i will correct it and will then apply script.
Hello, here I am posting my query again with modified data input files.
see my query is :
i have two input files file1 and file2.
file1 is smalldata.fasta
