+
+**TIP**
+
+This tool extracts a unique feature identifier from  GVF/GFF3 format, primarily to enable downstream analysis of SNPs or marker design
+
+
+----
+
+**Example**
+
+*input GFF3*
+
+::
+
+ ##gff-version 3
+ 1119927 gsMapper        SNP     434     434     .       .       .       ID=1119927:gsMapper:SNP:434;Reference_seq=G;Variant_seq=A;Total_reads=10;Variant_freq=100;Enzyme=AluI;Phase=variant
+ 1120709 gsMapper        SNP     361     361     .       .       .       ID=1120709:gsMapper:SNP:361;Reference_seq=T;Variant_seq=C;Total_reads=22;Variant_freq=68;Enzyme=TaqI;Phase=variant
+ 1120709 gsMapper        SNP     704     704     .       .       .       ID=1120709:gsMapper:SNP:704;Reference_seq=A;Variant_seq=G;Total_reads=20;Variant_freq=90;Enzyme=RsaI;Phase=variant
+
+*output tabular text*
+
+::
+
+ 1119927:gsMapper:SNP:434
+ 1120709:gsMapper:SNP:361
+ 1120709:gsMapper:SNP:704
