In your calls to delete:
SN{mm}{1} is the folder name.
aa(nn).name is the file name.
so why are appending e.g. 'main*' ? You will get path/names like
/home/data/PRES/s01/main_abc.txt/main*
which is not what you want. You should either use the pattern 'main*' when you build the call to DIR, e.g. (untested)
SN = {{'s01', 1:6}, {'s02', 1:6}} ;
patterns = {'main*', 'p*', 'ap*'} ;
root_dir = '/home/data/PRES' ;
for dirId = 1 : numel( SN )
dirPath = fullfile( root_dir, SN{dirId}{1} ) ;
if ~exist( dirPath ), continue ; end
for patId = 1 : numel( patterns )
content = dir( fullfile( dirPath, patterns{patId} )) ;
for fileId = 3 : numel( content ) % 1 is '.', 2 is '..'
delete( content(fileId).name ) ;
end
end
end
or loop over all files and match relevant files according to patterns.
