Group stats for only certain groups within all of them

I have this excel file. I want to do group stats on the second column. but only for ABBA and CCCC

clear
[~, ~, data] = xlsread('Book1.xls',1);

species = data(:, 1);

split = data(:, 2);

X = cell2mat(split);

[grp1,grp1c,grpMin1,grpMean1,grpMed1,grpSem1,grpMax1,s21,grpStd1,grp951,grpskew1,grpkurt1] = grpstats(X,species({'ABBA' 'CCCC'}),...
    {'gname','numel','min','mean','median','sem','max','var','std','meanci',@skewness,@kurtosis},'Alpha',0.05);

Is there any way to do this? I keep getting error subindex not valid for this part

species({'ABBA' 'CCCC'})

My actual dataset is 10000 rows and all different ones are mixed in.

Any help would be appreciated! Thanks
