Textscan to extract data from text file

This is a followup to a previous question I posted here. In my original question I forgot to mention that I also need to extract the following lines from each specimen in the same pass/loop:

    Width:            0.5040000 in
    Thickness:        0.0350000 in
    Spec gauge len:   7.0000000 in
    Ext. gauge len:   8.5000000 in

My attempts to modify the code provided by dpb (below) result in the error "Subscripted assignment dimension mismatch"

fid=fopen('Sample_DATA.TXT','r');  % open file 
N=cell2mat(textscan(fid,'Number of specimens: %d %*[^\n]','headerlines',11));
for i=1:N                                % loop over number specimens in file
  l=fgetl(fid);                          % initialize string to find start of section
  while isempty(strfind(l,'Specimen:')),l=fgetl(fid);end  % find the Specimen: n start
  while isempty(strfind(l,'_')),        l=fgetl(fid);end  % then line break before data
  d(i)=textscan(fid,'','delimiter',',','collectoutput',1); % the nth specimen data set
end
fid=fclose(fid);

Any suggestions? The text file is attached.

How did you initialize d ?

Which line is the error occurring on?

Sorry for the confusion. The code above is working fine for that it's meant to do (extract the 500+ rows of data for each specimen).

I am trying to modify it so that it also extracts (lines 54-57 for specimen 1)

    Width:            0.5040000 in
    Thickness:        0.0350000 in
    Spec gauge len:   7.0000000 in
    Ext. gauge len:   8.5000000 in

for each specimen and saves it to a cell array. Similar to d.

The errors occured when I tried to modify it.
