description of this run

I want to specify chromosomal landmarks and use a local copy of the HapMap
I want to upload a HapMap genotype file
I want to upload my own genotype data as a PED file
I want to upload my own genotype data which is phased and in Nick Patterson format

chromosomal landmarks
Enter the genomic regions that you want to tag
using NCBI Build 35/UCSC hg17/May 2004 coordinates
Example: chr10:114,700,200..114,916,057
HapMap analysis panel:

This uses the phased HapMap Release 21 (incl. chrX)

YRI: 2,937,220 polymorphic SNPs
CEU: 2,623,164 polymorphic SNPs
CHB+JPT: 2,480,469 polymorphic SNPs
SNP design scores (for preferential SNP picking)
default design scores for all SNPs:
include tag SNPs exclude tag SNPs
 only evaluate these SNPs (do not pick extra tags) exclude all SNPs with design scores <
which alleles do you want to capture? minimum allele frequency
 all SNPs (above frequency threshold)
 only these specified alleles:
for SNPs:
for haplotypes (if you specified any):
Tagger mode r2 threshold
 aggressive (specified multimarker tests)
for SNPs:
for haplotypes (if you specified any):
advanced settings
maximum number of markers in haplotype tests:
LOD score threshold:
maximum number of tries:
maximum tagging distance:
 pick only the N best tags 
minimum distance between tags:  base pairs
