READ  ME:
        These  files contain information about the S. cerevisiae deletion strains.  The following is a list of all available  columns and descriptions.  
        Columns  and descriptions are:
        1.  Rec_num:  Record numbers refer to  each of strain backgrounds:
  >10,000:  mat a haploids
          10,000-19,999:   mat  alpha haploids
          20,000-29,999:   heterozygous  diploids
          30,000-39,999:     homozygous diploids  
          Four  digit numbers preceded by an “n” are general record numbers and are not  indicative of any strain type.  For a description  of the genotypes, see here
        2.  ORF name:  Systematic name from SGDTM, named  from the time of strain generation.  Caveats:  This means an ORF name may now be considered  an alias name.  For example, YJL206C-A and YJL205C-A  are aliases of YJL205C (gene name: NCE101), but the deletion strain name is under the historical  name:  YJL206C-A.
        3.  deletion_ alias: Appended characters to the ORF name distinguishes multiple deletions:
          _t:   denotes a truncated, or partial deletion
          _d:  deleted  or removed ORF in SGD
        _1:  numbers distinguish  deletion strains with the same name
        4.  Essential:  Disruption of ORF is lethal;  strain is in the heterozygous background only.
