Dear all, I faced a strange issue while I was trying to run CCP4-chainsaw. I used EBI-Clustal omega to prepare the desired alignement. Next, I copied the output into a text file and renamed it to alignment.aln. When I chose this file in chainsaw it gave me back this kind of error:
format error in ALN/Clustal file No CLUSTAL keyword This is the first line of my file : *CLUSTAL O(1.2.4) multiple sequence alignment* I also typed CLUSTAL W instead of CLUSTAL O but ccp4 gave me the same error message. Any suggestion will be appreciated. Kindly, Vicky
