+# TNT Script used by Guoyi
+
+This scripts are followed MIT except for setk.run which belongs to Salvador Arias(Instituto Miguel Lillo, San Miguel de Tucumán, Argentina).
+
+## tnt.run
+
+- `file.tnt` must be changed to your own file;
+
+- `trees.tre`, `bt.tre` are trees with taxaname;
+
+- `trees_no.tre`, `bt_no.tre` are trees without taxaname which can be put into Winclada with the `file.tnt`;
+
+- `majority` can be replaced by `nelsen`;
+
+- `boot` can be replaced by `jack`;
+
+## setk_tnt.run
+
+- `file.tnt` must be changed to your own file;
+
+- You can find the recommended k from `setk.log` and then change in `piwe=` `tnt.run`;
