how to handle this issue "Error using regexprep"

Hello @ ALL I am using PLS-SEM. An error occure "Error using regexprep All cells must be char row vectors."

LMV_labels is 14×1 cell array consist of

{["usm1" ]}

{["usm2" ]}

{["usm3" ]}

{["usm4" ]}

{["owrl1"]}

{["owrl2"]}

{["owrl3"]}

{["owrl4"]}

{["crt1" ]}

{["crt2" ]}

{["crt3" ]}

{["crt4" ]}

{["crt5" ]}

{["crt6" ]}

I want to convert them in the format like

{ 'usm1' }

{ 'usm2' }

and so on.....

% Assuming this is what you have...
labels = {{["usm1" ]} ,{["usm2" ]},{["usm3" ]},{["usm4" ]},...
    {["owrl1"]},{["owrl2"]},{["owrl3"]},{["owrl4"]},{["crt1" ]},...
    {["crt2" ]},{["crt3" ]},{["crt4" ]},{["crt5" ]},{["crt6" ]}};

% then you can convert using cellfun
newlabels = cellfun(@(v) char(v{1}),labels, 'UniformOutput',false);

I don't see how this is an issue with regexprep at all...
