I use spdfcdfinfo and spdfcdfread for loading cdf files to matlab. Occasionally the cdf files can be corrupted on a data server and then these two cdf scripts crash whentrying to load data to matlab. Is there any method to check that the cdf file is readable before trying to use spdfcdfinfo and spdfcdfread?

One approach is to use the built-in MATLAB function exist to check if the file exists and is readable.
Another approach is to use the “cdflib” function “cdflib.open” to open the CDF file and check if it is readable.
To avoid the program crashes, always use try-catch blocks. Put the code using which you are checking the file inside the try block and put the corresponding catch block.
Go through the below documentations:
Documentation for exist function.
Documentation for CDF Library.
Documentation for try-catch blocks.
