Hi Folks


Iam a new user in perl and I have two questions .Hopefully I get any help


my data like that


Chr1    TAIR10  chromosome      1       30427671        .       .       .       ID=Chr1;Name=Chr1
Chr1    TAIR10  gene    3631    5899    .       +       .       ID=AT1G01010;Note=protein_coding_gene;Name=AT1G01010
Chr1    TAIR10  mRNA    3631    5899    .       +       .       ID=AT1G01010.1;Parent=AT1G01010;Name=AT1G01010.1;Index=1
Chr1    TAIR10  protein 3760    5630    .       +       .       ID=AT1G01010.1-Protein;Name=AT1G01010.1;Derives_from=AT1G01010.1

Chr1    TAIR10  CDS     3760    3913    .       +       0       Parent=AT1G01010.1,AT1G01010.1-Protein;
Chr1    TAIR10  exon    3996    4276    .       +       .       Parent=AT1G01010.1
Chr1    TAIR10  CDS     3996    4276    .       +       2       Parent=AT1G01010.1,AT1G01010.1-Protein;
Chr1    TAIR10  exon    4486    4605    .       +       .       Parent=AT1G01010.1

Chr1    TAIR10  exon    4706    5095    .       +       .       Parent=AT1G01010.1
Chr1    TAIR10  CDS     4706    5095    .       +       0       Parent=AT1G01010.1,AT1G01010.1-Protein;
Chr1    TAIR10  exon    5174    5326    .       +       .       Parent=AT1G01010.1
Chr1    TAIR10  CDS     5174    5326    .       +       0       Parent=AT1G01010.1,AT1G01010.1-Protein;

I need to use Hash  to answer these questions

1: output a file that has Gene name in column 1 and the number of exons it contains in column 2

2: output a file that list all the transcripts/mRNA in column 2 and the gene it is found in column 1
