Parfor Can not convert cell to double

Hello guys.

I have a problem with parfoor loop usage.

I have cell including protein sequences and their ids. I want to consider the sequences only and i need to add sequences to the another cell.

The code below is working

i = 1
while i < length(sampleProtein)
    for k=2:2:length(sampleProtein)
    X(i,:) = sampleProtein(k)
    i = i+1
    end
end

Yet, when i use parfor it gives me an error "Conversion to double from cell is not possible"

parfor i=1:length(sampleProtein)
    for k=2:2:length(sampleProtein)
        X(i,:) = sampleProtein(k)
    end
end

Can you guys help me out?

parfor i=1:length(sampleProtein)
        X{i} = sampleProtein{2*i};
end

Thank you mate. It is worked. Really appreciated.

The upper bound should probably be length(SampleProtein)/2

[Walter Roberson]

But probably you should just skip the parfor and do

X = sampleProtein(2:2:end);

Thank you again mate. I will check it.
