loading .txt file
显示 更早的评论
Hi, How do I load a file like this (3 lines):
-------------
#A=AY/func/7_corrs/broca_4mm_Z_2standard.nii.gz B=AY2/func/7_corrs/broca_4mm_Z_2standard.nii.gz
--------------
#A #B #(A uni B) #(A int B) #(A \ B) #(B \ A) %(A \ B) %(B \ A) Rx(B/A) Ry(B/A) Rz(B/A)
--------------
127239 173524 204106 96657 30582 76867 24.0351 44.2976 0.9209 0.9803 1.3314
---------------
What I want to extract in Matlab is..
#A = 127239
#B = 173524
#(A uni B) = 204106
etc...
Thank you,

Can you please fix the formatting to show how the file appears. Thanks. Also, can you explain more how you want MATLAB to extract and package the information: do you want strings "#A = 127239" or variables A, B, etc with values 127239, ... Do you want those labels (A, B, ...) to be fixed or taken from a line of the file. And so on.

If you don't need individual variable names then I'd probably go with the simplest approach of
data = dlmread('data.txt','',2,0);
If you have missing values or error codes or other weirdness, then use textscan.
If you have Statistics Toolbox, another approach would be to use dataset to import the data as a dataset array:
data = dataset('File','data.txt','headerlines',1);
The downside is that the variable names will be hideous, due to all the non-valid characters. If you wanted to get vaguely fancy (and had some pattern to how to interpret the names), you could use regexp:
fid = fopen('data.txt','rt');
hdr = fgetl(fid);
hdr = regexp(fgetl(fid),'\t','split');
fclose(fid);
hdr = regexprep(hdr,'#','No_');
hdr = regexprep(hdr,'%','Perc_');
hdr = regexprep(hdr,'\W','');
data = dataset('File','data.txt','headerlines',1);
data.Properties.VarNames = hdr
