我是一个相当新的 Circos 用户，我试图让 Circos 不显示任何低于一定长度的链接，比如说 10000。这是我当前的链接部分，包括规则：

<links>

    z = 5

    radius = 0.65r
    bezier_radius = 0.4r
    bezier_radius_purity = 0.45
    crest = 0.4
    perturb = yes

    <link segdup>
        show = yes
        color = black_a8
        thickness = 2
        record_limit=5000
        file = minDist_10K_KO.circos.interactions.txt
                    <rules>
                        <rule>
                                importance = 205
                                condition = _THICKNESS1_ > 20
                                thickness = 20
                        </rule>
                        <rule>
                                importance = 185
                                condition = abs(var(pos1) - var(pos2)) < 100000
                                show = no
                        </rule>   
                        <rule>
                                importance = 200
                                condition = _THICKNESS1_ < -20
                                thickness = 20
                        </rule>
                        <rule>
                                importance = 195
                                condition = _THICKNESS1_ < 0
                                thickness = eval(abs(_THICKNESS1_))
                        </rule>
                        <rule>
                                importance = 190
                                condition = _THICKNESS1_ < 1
                                thickness = 1
                        </rule>
                </rules>
    </link>
</links>

应该改变事物的规则是第二条规则，即：

                    <rule>
                            importance = 185
                            condition = abs(var(pos1) - var(pos2)) < 10000
                            show = no
                    </rule>

但是，无论我将值更改为什么，图像中显示的链接都不会改变。此外，现在线条非常细——不太清楚为什么还会发生这种情况。我试过改变规则的重要性，但这也不起作用。最后，这是我的交互文件示例：

有人知道发生了什么吗？
