Hi friends

I installed Tophat2 with all dependencies (bowtie2, Boost, Samtools) but when I want to run tophat, it shows this error:

```
File "/home/tophat-2.0.14/bin/tophat", line 1003
    except getopt.error, msg:                       ^
SyntaxError: invalid syntax
```

My python version is 3.4 , how can I fix this problem?

Thanks
Try installing python2.
