Top Forums Shell Programming and Scripting Check whether a given file is in ASCII format and data is tab-delimited Post 302116201 by Mandab on Wednesday 2nd of May 2007 09:41:47 AM

I am totally confused now.
Since I am a newbie and wrote the above script with the help of this forum.
I'll get a file which is tab delimited and from 3rd line onwards it has data. First field is numeric(9) not null and second field is char(8) not null, third field is numeric(9) null and fourth field is (13) not null. My requirement is first to check whether it is in tab-delimited format or not. If it is not then generate error and put it in var1 "101" and var2="Not in tab-delimited format" and if it is in tab-delimited format then check whether first field datatype and length and also for not null value, if doesn't match then var1 "110" and var2="Mismatch/Wrong Field one" if matches then check second field and put var1= "120" and var2= "Mismatch/Wrong Field two" and so on. I want to use var1 and var2 to be used for other computation. Whatever comments you have written above have gone over my head. Please help me.

NAME
vcf-isec - create intersections, unions, complements on bgzipped and tabix indexed VCF or tab-delimited files SYNOPSIS
vcf-isec [OPTIONS] file1.vcf file2.vcf ... DESCRIPTION
About: Create intersections, unions, complements on bgzipped and tabix indexed VCF or tab-delimited files. Note that lines from all files can be intermixed together on the output, which can yield unexpected results. OPTIONS
-C, --chromosomes <list|file> Process the given chromosomes (comma-separated list or one chromosome per line in a file). -c, --complement Output positions present in the first file but missing from the other files. -d, --debug Debugging information -f, --force Continue even if the script complains about differing columns. -o, --one-file-only Print only entries from the left-most file. Without -o, all unique positions will be printed. -n, --nfiles [+-=]<int> Output positions present in this many (=), this many or more (+), or this many or fewer (-) files. -p, --prefix <path> If present, multiple files will be created with all possible isec combinations. (Suitable for Venn Diagram analysis.) -t, --tab <chr:pos:file> Tab-delimited file with indexes of chromosome and position columns. (1-based indexes) -w, --win <int> In repetitive sequences, the same indel can be called at different positions. Consider records this far apart as matching (be it a SNP or an indel). -h, -?, --help This help message. EXAMPLES
bgzip file.vcf; tabix -p vcf file.vcf.gz bgzip file.tab; tabix -s 1 -b 2 -e 2 file.tab.gz vcf-isec 0.1.5 July 2011 VCF-ISEC(1)
