Unable to perform assignment because brace indexing is not supported for variables of this type

Here is the line of my script that I am struggling with

run{1,1} = Y1( 1 : R1(1) );

Where R1(1)=244, When I write like this : run{1,1} = Y1( 1 : 244 ) it is okay

but with R1(1) I get this error

Unable to perform assignment because brace indexing is not supported for variables of this type

[MarKf]

Usually I stumble on "variables of this type" error because variables are already present in the workspace and I do not clear/preallocate/initialize (for quick implementations/testing, sometimes switching and running back and forth between cells). If it's really just a scalar, R1 does not sound like it's the issue here, but variable run might be (also I'd suggest not to call it a common command, run1 already works better)

Yeah I just figured out that run was used before in a loop

Thanks

You need to provide more context.

For example, this is OK.

run = cell(10,1);
R = 244:300;
Y = 1:300;
run{1} = Y(1:R(1))

run = 10×1 cell array
