[chimerax-users] missing or invalid sequences

[Liang, Junyi]

I would like to predicate interaction between two proteins, and tried chimerax version 1.5 after noticing a youtube video https://www.youtube.com/watch?v=6lXeCPuTePs.

Running AlphaFold to Predict Protein Complexes from ChimeraX<https://www.youtube.com/watch?v=6lXeCPuTePs>
How to predict the structure of a photoreaction center complex of 3 proteins from ChimeraX using AlphaFold-Multimer. Requires a ChimeraX daily build newer than December 2, 2021 or version 1.4. It is not in ChimeraX version 1.3. Web page describing steps https://www.rbvi.ucsf.edu/chimerax/data/alphafold-dec2021/af_multimer.html

I input the two protein sequences in same way as shown in the video and hit predict. But your software says "missing or invalid sequences". How come?
