Regarding CPLEX error

[SANKAR MAHESH R]

Hi.

I'm using CNA's function as an API to compute a pathway's MDF as per ASTHERISK.

When I run the program, I get a Java exception.

 

Java exception occurred:
ilog.cplex.CpxException: CPLEX Error  1426: Low-level file I/O error.


    at ilog.cplex.CplexI.CALL(CplexI.java:5204)

    at ilog.cplex.CplexI.init(CplexI.java:7283)

    at ilog.cplex.CplexI.<init>(CplexI.java:866)

    at ilog.cplex.IloCplex.<init>(IloCplex.java:12991)

    at IloCplexMIPmat.<init>(IloCplexMIPmat.java:29)


Error in max_min_driving_force_pathway_ratio_range (line 194)
  obj= CplexJava();

Error in generateToyModelReport (line 49)
finalReport = astherisc(targetSubstrateReaction, targetMaxSubstrateUptake,...

I tried looking up this on the internet but could not further proceed since IBM's manual CPXERR_FILE_IO - IBM Documentation did not have clear ways of troubleshooting.

It will be very helpful if some one can help me overcome this error.

Hi,

have you checked that you have write permission and that there is disk space available?

Does this error already occur when you execute

obj= CplexJava();
in the Matlab console?

When I execute obj = CplexJava(), I still see the same error in the MATLAB console.

>> obj=CplexJava()

Warning: The following error was caught while executing 'CplexJava' class destructor:

Dot indexing is not supported for variables of this type.

Error in CplexJava/delete (line 191)

      obj.cpx.end(); %A prevents memory leak

Error in CplexJava (line 38)

      global cnan;

Error using CplexJava (line 42)

Java exception occurred:

Also, it will be useful to know the directory name for which I should check write access.

Hi,

does calling "javaObject('IloCplexMIPmat')" on the Matlab console work?

Is there a field "cnan.cplex_remote" and what are its contents? Remove it with "cnan = rmfield(cnan, 'cplex_remote')" and try "CplexJava()" again.

-Axel

Hi.

Removing the field in cnan named cnan.remote with the command shared above the error could be resolved.

Thanks, Axel.
