problem when the first input of normcorre.m is a pointer to .mat file #10

Closed smile347 closed 7 years ago

smile347 commented 7 years ago

line 35-38 in function normcorre.m

elseif strcmpi(ext,'mat') filetype = 'mem'; Y = matfile(Y,'Writable',true); sizY = size(Y);

This would not return the size of the data, it should be sizY = size(Y.Varname)

Hi @smile347 thanks for bringing this into my attention. I'll need to modify the code to accept an arbitrary variable name in the mat file. In the meantime, you can load the data in memory (if not too large), and pass it as an array, or read the data directly from the hard drive using a different file format.

@smile347 I believe the bug is now fixed. The function will scan the mat file and consider the variable with the largest size as the data to be corrected. Let me know if problems persist.
