[Genome] extracting genomic regions from locations

[Веселин Баев]

Dear All,
how can I retrieve sequences from locations like this automatically:

chr----start-----stop-----strand
9	108464802	108464823	-
11	110286355	110286377	+
14	101472070	101472091	+
14	101471691	101471712	+
14	101487793	101487815	+
7	137472049	137472068	+
X	49940888	49940909	+


Thanks!
Vesko
