MakeBlastDb has several warning handled has error which is problematic on galaxyn This groomer ensure that the fasta file will not generate this warnings / error :
- First line of the sequence is more than 40% of N => replace all the 'N' of the first line by 'a' (not elegant but low impact and efficient)
- Header line should not have [xxx=xxx] kind of text because MakeBlastdb try to interpret it => remove the [] when this feature is detected
