Can't import more than one file using MFFMatlabIO #27

Closed AlanAHartley closed 4 years ago

AlanAHartley commented 4 years ago

I am able to import a single Netstation MFF file using MFFMatlabIO without difficulty. But then, when I later attempt to import another file, I get the error message "No class com.egi.services.mff.api.LocalMFFFactoryDelegate can be located on the Java class path. (Error occurred in function mff_importsignal() at line 46)"

I am guessing this may be related to "When the Java Heap Memory is at its default level, few files can be imported. There is a special message guiding users how to increase the default settings in Matlab in case they encounter an error. Importantly, some large files require a computer with 16Gb of RAM or more (or Java Heap of 4Gb)." But there is no message about increasing space.

Running EEGLAB 2019 under MATLAB e2020a and Win10. i7 processor with 8Gb.

Any guidance would be greatly appreciated.

I think it might be related to the fact that you have the MFFimport plugin installed as well. Would you mind to check.

AlanAHartley commented 4 years ago

Thanks for the suggestion. It doesn't appear that I have MFFImport installed: EEGLAB: adding "Cleanline" v1.04 (see >> help eegplugin_cleanline) EEGLAB: adding "ICLabel" v1.2.6 (see >> help eegplugin_iclabel) EEGLAB: adding "MFFMatlabIO" v3.4 (see >> help eegpluginmffmatlabio) WARNING: for plugin "SASICA" version in the folder name "1.3.4" and in the eegplugin file ".1.3.7" differ EEGLAB: adding "SASICA" v1.3.4 (see >> help eegplugin_SASICA) EEGLAB: adding "clean_rawdata" v2.1 (see >> help eegplugin_clean_rawdata) EEGLAB: adding "dipfit" v3.3 (see >> help eegplugin_dipfit) EEGLAB: adding "erplab" to the path; subfolders (if any) might be missing from the path EEGLAB: adding "firfilt" v2.4 (see >> help eegplugin_firfilt)

Yes, it could be the Java heap although the error is different. Did you try increasing the heap. Send me a datafile (through Google Drive or Dropbox if you think it might help).

No, I didn’t try that. How do I increase the Java heap?

Yes, indeed, increasing the Java Heap to 1059 allowed me to import another file without difficulty.

Thanks! Alan

Correction. Increasing the Java heap allowed importing two files but the third one produced the same error. I could probably increase the heap further but I'm guessing that would just up the limit a bit. These are 256 channel X 250 Hz X 30 min recordings so size probably matters.

Yes, although importing files one after the other should not be a problem because heap memory should be release. Maybe there is a bug in the Java implementation?

Correction. Increasing the Java heap allowed importing two files but the third one produced the same error. I could probably increase the heap further but I'm guessing that would just up the limit a bit. These are 256 channel X 250 Hz X 30 min recordings so size probably matters.
