PercolatorTabWriter style issue #114
Comments
|
Update: Using the '.pin' extension worked. |

Hi Caroline! Thanks for reporting! This was indeed a bug. If style is not passed explicitly, it is inferred from the file extension. This is why it did work in your update. However, if it was passed, no inference happened (as intended), but the value was still not set when it should have been. Will be fixed in the upcoming release. Best, |

Hej, thanks for a nice library. :) I am trying to convert and write to Percolator pin format but I seem to get some issues related to the style parameter.
