The error "Conversion to cell from char is not possible" occurs due to incorrect data type conversion. For example, the error can be reproduced in the following scenario:
X = {9};
X(1) = 'a';
To correct the above code, the following curly braces can be used:
X(1) = {'a'};
I would also suggest you go through the following MATLAB documentation page to understand cell arrays and how to access data from cell arrays:
If the problem continues, sharing your code could help in resolving it.
I hope the above information is helpful!
