Loading text file with header and using Textscan yeilding empty array

I am unable to load data in txt file with header information using fopen and textscan. Below is the header type and the numeric data follows.

/datum  10000.00
/0057841A
/60Hz AC filter
/13.5V
/tune initialize N auto-tune Y 048.8uT
/time nT sq 
000002.0  48812.27 99 
000007.0  48812.26 99 
000012.0  48812.27 99 
000017.0  48812.31 99 
000022.0  48812.26 99 

I have tried using the following code but the data array has empty value irrespective of the last step. I know there's a silly error in my code. Would like to request for correction. Thanks in advance. One more question: How can I load this txt file in matlab and simply replace the '/' of header information with '%'?

fid=fopen('file.txt','r');
data=textscan(fid,'%f%f%d','HeaderLines',6); 
data=cell2mat(data);

Your code works fine, not sure what is the problem.

Another way is to use importdata()

out=importdata('file.txt',' ',6)
str=strrep(out.textdata(:,1),'/','%')

importdata works fine but I wanted to use the fid method. Anyways, thank you.
