I have downloaded MINT Dataset for Human Protein Protein Interactions. The Link from where I downloaded the dataset is here..-->>> ftp://mint.bio.uniroma2.it/pub/release/txt/current/2012-10-29-mint-human.txt
The dataset is last updated in 2012. Actually my question is that the dataset contains to many fields in the columns of baits and preys as blank entries denoted with dash. That means the baits field is blank and the preys field has the protein name. And also there are some fields with Not protein names but they contain baits and preys fields with numeric entries instead of character names of proteins. And there are some field which are having non-human fields entery and also there are some baits and preys field contain the several protein names for a single column. So do I need to filter out these fields or should I keep these fields?
