Can somebody point out how I have to modify the code below to allow it being used in a parfor loop

H = height(RTImport)
location = 'location..'
ds = datastore(location)
TT = tall(ds)
func = @(x) mean(x,'omitnan');
x1{H} = {};
x2{H} = {};
tic
    for i = 1:H    
      Strt = minutes(RTImport.Start(i))
      endT = Strt + minutes(1)
      S = timerange(Strt,endT,'closed')
      TT1 = TT(S,:)
      
      Strt = Strt + minutes(1)
      endT = Strt + minutes(1)
      S = timerange(Strt,endT,'closed')
      TT2 = TT(S,:)
     
      x1{i} = varfun(func,TT1,'OutputFormat','table')
      x2{i} = varfun(func,TT2,'OutputFormat','table')
      
      gather(x1{:},x2{:})
    end
toc

I get the information unable to classify x1 in the body of the parfor. Going through the information, I couldnt really figure out what wrong with it...Appreciate any help
