I have some questions on edf to mat.

I'm Sheldon Zhang. I get the Edfread.m from MathWorks. I want to change edf to mat,but I'm new on Matlab.

When I type "hdr = edfread('SZ2-3.edf')" It shows like this: Step 1 of 2: Reading requested records. (This may take a few minutes.)...

hdr =

            ver: 0
      patientID: 'VEEG0118N_1 M 07-SEP-2006 ##_#                                                  '
       recordID: 'Startdate 12-JUN-2017 X X Compact_2x64ch                                        '
      startdate: '12.06.17'
      starttime: '04.37.36'
          bytes: 29440
        records: 2138
       duration: 1
             ns: 114
          label: {1x114 cell}
     transducer: {1x114 cell}
          units: {1x114 cell}
    physicalMin: [1x114 double]
    physicalMax: [1x114 double]
     digitalMin: [1x114 double]
     digitalMax: [1x114 double]
      prefilter: {1x114 cell}
        samples: [1x114 double]
      frequency: [1x114 double]

Some of variables like 'physicalMin','digitalMin','digitalMax','samples' and 'frequency' are 'NaN'. I don't know how it happend.

And if I type [hdr,record] = edfread('SZ2-3.edf'); It shows like this:

Step 1 of 2: Reading requested records. (This may take a few minutes.)... Error using fread Invalid size.

Error in edfread (line 225) tmpdata(recnum).data{ii} = fread(fid,hdr.samples(ii),'int16') * scalefac(ii) + dc(ii);

It seems the code can't run.

I would appreciate it if you can give me some advice! Thank you very much!!!

I'm a student from China. I had the same question with you. Have you solved your problem? If yes, could you give me some advice?

I had the same question with you, too. Could you give me some advice on how you solve this problem？
