File B sample

AT5G46880.1
AT5G27818.1
AT5G77690.1

the desired output in this case should be

 AT5G46880.1  317     555

it should show the id and values from column 7 and 8 ie, alifrom and ali to.

Files A and B are much larger than the provided samples. What I want is match each ID line from file B to A, and if there is match in file A (ID after >>), then print the values in the alifrom and alito columns to a new file along with the id. The data alignments for each domain are not needed.

I think to first delete unnecessary data from file A and store first five lines starting from >> till Alignments for each domain then compare. but don't know how to proceed.

note: file A is not tab delimited

  • Please add to your question the desired output for the two example files you have above, so we know what format you want the output to look like. Do you want a separate file for each "id"? Commented May 13, 2015 at 16:20

With the subsequent awk program:

awk '
  BEGIN             { FS = "([[:space:]]+|[|])" }
  NR==FNR           { id[$1] ; next }
  /^>>/ && $2 in id { data = $2 ; f = 1 }
  f && /^[0-9]/     { data = data " : " $10 " " $11 }
  f && !NF          { f = 0 ; print data }
' FileB FileA

you will get this output:

AT5G46880.1 : 317 555
AT1G73360.1 : 230 457 : 544 566

Note: I've added the second ID to FileB so that you can see how multiple attribute lines will be handled.

How the awk program works:

BEGIN - the field separator is defined so that we can later esily access the ID from lines starting with ">>".

NR==FNR - this is a pattern that is true while reading the first file; the ID's are stored.

/^>>/ && $2 in id - we match lines with the IDs and check whether the found ID had been memorized from the first file. The ID is saved for output and a processing flag set.

f && /^[0-9]/ - if the flag is set and we match a line starting with a digit we add the respective fields 10 and 11 to the output data (separated by a colon).

f && !NF - if the flag is set and an empty line is found then the processing is done for that block and the flag cleared.

    First, the file order should be FileB FileA according to your script, right? Second, I think the desired fields are 10 and 11 not 7 and 8. Perhaps OP could clarify whether or not $12 should be included as well. Commented May 13, 2015 at 16:30

  • @user106326; I have tested the awk program with the data you posted and it worked; the output I posted is what was shown on stdout. Please re-inspect carefully what you've done. (An empty output may be an indication of switched files A and B. - The first file argument, FileB, must contain the IDs, and the second file argument, FileA, must contain the actual data to parse.)

  • sorry for my fault. yes it works. there were some alterations in file A. it works like miracle. and thank you for the follow through of the command. thanks a lot Commented May 14, 2015 at 10:13

Try this

grep -A4 -f <(sed 's/^/^>> /' fileB) fileA | 
    sed -r '/^>>/! s/(\S+\s+){8}((\S+\s+){3}).*/\2/
            s/[][>.-]*\s*//'
