Hello! I'm trying to loop over a series of hdf files inside a folder. I get the map for the first iteration but fail to continue. Can somebody let me know what is the error that is causing the loop to stop in the second iteration? Thank you
clear all
close all
clc
cd('E:\MOD05_Jan2008')
files = dir('*.hdf');
for k = 1:numel(files)
lat=double(hdfread(files(k).name, '/mod05/Geolocation Fields/Latitude', 'Index', {[1 1],[1 1],[406 270]}));
lon=double(hdfread(files(k).name, '/mod05/Geolocation Fields/Longitude', 'Index', {[1 1],[1 1],[406 270]}));
WV=double(hdfread(files(k).name, '/mod05/Data Fields/Water_Vapor_Infrared', 'Index', {[1 1],[1 1],[406 270]}))*0.001;
latlim = [min(min(lat)) max(max(lat))];
lonlim = [min(min(lon)) max(max(lon))];
fir = find(WV<0);
WV(fir) = NaN;
cd('C:\Users\Guest\Desktop')
figure(1)
axesm('mercator','MapLatLimit',latlim,'MapLonLimit',lonlim,'MeridianLabel','on', ... 'ParallelLabel','on');
surfm(lat,lon,WV)
colorbar

ylabel('Latitude')
end

-Are you sure you don't just get the map from the last one?
-If there is an error, what is it?

You are switching to another directory
cd('C:\Users\Guest\Desktop')
it means that it cannot find the files with name files(k).name in 'C:\Users\Guest\Desktop'
Use:
hdfread(fullfile('path to hdf files', files(k).name),...)

Thaks Oleg! I made the correction but now get this error:
Undefined function 'eq' for input arguments of type 'cell'.
Error in fullfile (line 39)
elseif (f(end)==fs) || (part(1)==fs || (bIsPC && (f(end)=='/' || part(1)=='/')) )
Error in modis2 (line 10)
lat=double(hdfread(fullfile('E:\MOD05_Jan2008', files(k).name, '/mod05/Geolocation Fields/Latitude', 'Index', {[1
1],[1 1],[406 270]})));
Thanks for your help
