b. Block Parameters

s. Saving Options

g. Get Blocks

q. Quit


Your Choice:</pre>此时可以选择<code>b</code>更改一些数值

BLOCK PARAMETERS<pre>1. Minimum Number Of Sequences For A Conserved Position: . 21
2. Minimum Number Of Sequences For A Flank Position: ..... 34
3. Maximum Number Of Contiguous Nonconserved Positions: .. 8
4. Minimum Length Of A Block: ............................ 10
5. Allowed Gap Positions: ................................ None

r. Restore Defaults
g. Get Blocks

z. Extended Block Options
m. Go To Main Menu


Your Choice:</pre>输入对应选项可以修改，也可以不修改，此处不修改，直接选择<code>g</code><pre>exampleout.fas
Original alignment: 1085 positions
Gblocks alignment:  81 positions (7 %) in 4 selected block(s)</pre>此时根目录里<code>exampleout.fas-gb.htm</code>是保守区选择信息，将<code>exampleout.fas-gb</code>修改为<code>exampleoutgb.fas</code>或者其它以<code>fas</code>结尾的文件，得到了选择了保守区的序列。
