Hi, I am a beginner in bioinformatics and I am using homology modelling to predict the tertiary structure of a protein sequence. I am using SWISS-MODEL to construct the tertiary structure. However, I have also seen in many posts online that MODELLER is a tool that is used a lot to predict the tertiary structure of a protein. I would like to know that whether these two tools are as equally as good as each other, or are there certain advantages in using one of these tools over the other? Further, with regards to validating the structure created through homology modelling, I have read that the tools that you will need to use to validate the structure will differ depending on whether SWISS-MODEL or MODELLER is used. Is this correct? And when it comes to validating your structure, are there certain advantages in using one tool over the other to create the tertiary structure (e.g. SWISS-MODEL vs MODELLER)? I would really appreciate any insights from someone who has experience using these tools. Thanks.
