I am getting the following error while using Microsoft MSR ToolBox
Error using fread
Invalid file identifier. Use fopen to generate a valid file identifier.
Error in htkread (line 8)
nframes = fread(fid, 1, 'int32'); % number of frames
Error in DebugCode (line 13)
data{ix} = htkread(filenames{ix});
The code of functions where the errors arise are:
function gmm = mapAdapt(dataList, ubmFilename, tau, config, gmmFilename)
......
.
if ischar(dataList) || iscellstr(dataList),
dataList = load_data(dataList);
end
if ~iscell(dataList),
error('Oops! dataList should be a cell array!');
end
nfiles = length(dataList);
.
..
.......
end
*****************************************************************************
function data = load_data(datalist)
% load all data into memory
if ~iscellstr(datalist)
fid = fopen(datalist, 'rt');
filenames = textscan(fid, '%s');
fclose(fid);
filenames = filenames{1};
else
filenames = datalist;
end
nfiles = size(filenames, 1);
data = cell(nfiles, 1);
for ix = 1 : nfiles,
data{ix} = htkread(filenames{ix});
end
**************************************************************************************
function [data, frate, feakind] = htkread(filename)
% reads features with HTK format
%
% Omid Sadjadi <s.omid.sadjadi@gmail.com>
% Microsoft Research, Conversational Systems Research Center
fid = fopen(filename, 'rb', 'ieee-be');
nframes = fread(fid, 1, 'int32'); % number of frames %%ERROR
frate = fread(fid, 1, 'int32'); % frame rate in 100 nano-seconds unit
nbytes = fread(fid, 1, 'short'); % number of bytes per feature value
feakind = fread(fid, 1, 'short'); % 9 is USER
ndim = nbytes / 4; % feature dimension (4 bytes per value)
data = fread(fid, [ndim, nframes], 'float');
fclose(fid);
datalist.txt is a file with 6300 entries like
htkfiles\fadg0_si1279.htk
htkfiles\fadg0_si1909.htk
htkfiles\fadg0_si649.htk

One or more of the files named in that list do not exist relative to your current directory.
The code
fid = fopen(filename, 'rb', 'ieee-be');
would be better as
[fid, message] = fopen(filename, 'rb', 'ieee-be');
if fid < 0
error('Failed to open file "%s" because "%s", filename, message);
end

How did you get dataList. I downloaded from https://www.microsoft.com/en-us/download/details.aspx?id=52279 and it does not have database to train. Please let me know how you got database.

Its a bit late, but in case you are still stuck, here is the answer. You will need to prepare the dataList according to your data. The format is:
path_to_features\speaker1_utterance1.htk
path_to_features\speaker2_utterance2.htk
.
.
The one I have put above is for TIMIT database ( https://catalog.ldc.upenn.edu/ldc93s1 ) which is a paid database that can be purchased from LDC.
