How can I get cell2struct to work within my for loop? "error using cell2struct, Number of field names must match number of fields in new structure"

I am using a forloop to extract band powers from EEG data. I keep getting errors for the cell2struct funciton I use within my code. I want the output (store) to contain the aspects you can see in the store variable within a structure. The values are provided by the for-loop running function "compute_epoched_bandpower".

I just need to know how to fix the "error using cell2struct, Number of field names must match number of fields in new structure" I keep getting when referring to the line "temp1=cell2struct(temp, fields, 1)".

Any help would be massively appreciated!

dats = ALLEEG;
l = length(dats);
store = struct('setname', EEG.setname,'rel_bp_time_series_bands', rel_bp_time_series.band,'abs_bp_time_series_bands', abs_bp_time_series.band,'rel_bp_time_series_band_mean', rel_bp_time_series.band_mean,'abs_bp_time_series_band_mean', abs_bp_time_series.band_mean);
temp = []
temp1 = struct([])
for i = 1:l
    [rel_bp_time_series,abs_bp_time_series ] = compute_epoched_band_power(ALLEEG(:,i));
    eeg.setname = EEG.setname(i)
    temp = [ rel_bp_time_series.band, abs_bp_time_series.band,rel_bp_time_series.band_mean, abs_bp_time_series.band_mean]
    fields = {'rel_bp_time_series_bands','abs_bp_time_series_bands','rel_bp_time_series_band_mean','abs_bp_time_series_band_mean'}
    temp1 = cell2struct(temp, fields, 1)
    store = [ store temp1 eeg.setname]
end

Following the cell2struct documentation, if fields is a four-element cell array and dim is 1 then temp would have to be a cell array with four rows. It is unclear from your description what class the source fields have, but most likely you will need to actually define that four-row cell array, e.g. if the fields are horizontal cell vectors:

temp = [...
    rel_bp_time_series.band;...
    abs_bp_time_series.band;...
    rel_bp_time_series.band_mean;...
    abs_bp_time_series.band_mean];

or if they are horizontal numeric vectors:

temp = {...
    rel_bp_time_series.band;...
    abs_bp_time_series.band;...
    rel_bp_time_series.band_mean;...
    abs_bp_time_series.band_mean};

or whatever conversion you need to do to create a cell array of size 4x....
