[FieldTrip] ft_read_header didn't work on the matlab opened from terminal

[胡益衡]

Dear Mikkel and Konstantinos

I tried to add 'fieldtrip/external/mne' to the path, and it came out new errors as below which happened in pretty low-level functions. The matlab was on Ubuntu 20.04 on work station in our lab.

>> hdr = ft_read_header('/data/meg/IPRM/rawdata/009/meg/IPRM_run01_raw_trans_ref_tsss.fif');
Unrecognized field name "FIFF_PROJ_ID".

Error in fiff_read_meas_info (line 152)
        case FIFF.FIFF_PROJ_ID

Error in ft_read_header (line 1910)
    info = fiff_read_meas_info(filename);

I downloaded the fieldtrip package from this work station and tried ft_read_header in my own computer which was Ubuntu 22.04. It was fine in both cases.
I guess maybe something happened to the matlab on our lab's work station. I am going to reboot the work station some day to check if it will be helpful.

Thanks
Yiheng
