How to give the same name a Matlab output txt file through input text file?

Hello all!

I'm using an input from a text file in this format (bair0011_01.dat) and use that input to name my output file every matlab loop. I also need it to save plots that are generate in each loop. Follow below the code:

    [name,path]=uigetfile({'*.dat'},'Select File');
newfile= [path name];
fid=fopen(newfile,'rt');
data=textscan(fid,'%f%f',-1,'Delimiter','\t','HeaderLines' ,1);
fclose(fid);*

FYI: The data are in a dataset array, so I'm exporting through "export command".

Thanks in advance
