some file format correction

@pravsripad , because the names of scripts under dong_modified banch have changed, I can not add my new editions on it, so I made a new branch for showing the test suggestions about the new repo.
 
If do not delete '-raw', then 
```ruby
fica_name = fclean.strip('-raw.fif') + '-ica.fif'
fica_name
'109925_CAU01A_100715_0842_2_c,rfDC,bp1-45Hz-ica.fif'
```
based on function 'apply_ica', it made file ''109925_CAU01A_100715_0842_2_c,rfDC,bp1-45Hz-raw-ica.fif''
