a='D:\Seismic Data';
b=dir(fullfile(a));
L1=length(b);
for i=3:L1
c=dir(fullfile(a,b(i).name));
d=fullfile(a,b(i).name,c(7).name);
e=headerInfo(d);
f=e{6,6};
g=strsplit(f,':');
s1{i-2,:}=e{8,3};
s2{i-2,:}=e{5,6};
s3{i-2,:}=e{5,11};
s4{i-2,:}=g{1};
s5{i-2,:}=g{2};

Which line is the error on?
for i=3 it is working well but as i=4 then is could not load all the directory in c.

Are you sure you want to hard-code index of c to c(7) on line 5?

yes c(7) is hard-code index.
How can you be positive there will always be at least 7 files there?
Also you are not taking into account that the order of files returned is not fixed, and depends on the file system (not the operating system). If you need a particular name then you should use it.
