I have a file with multiple columns. I am showing two columns in which I am interested two columns

```
 Probe.Set.ID         Entrez.Gene
A01157cds_s_at               50682
A03913cds_s_at               29366
A04674cds_s_at 24860 /// 100909612
A07543cds_s_at               24867
A09811cds_s_at               25662
----                          ----
A16585cds_s_at               25616

```

I need to replace /// with "\t"(tab) and the output should be like

```
A01157cds_s_at;50682
A03913cds_s_at;29366
A04674cds_s_at;24860      100909612

```

Also, I need to avoid the ones with "---"
