[Eeglablist] Regarding .fdt files

[#HENG JIAMIN GLADYS#]

Dear EEGLab list,

I am using EEGlab version 13.4.4b. For preprocessing, I have been saving files after each step, and it has been producing 2 files: a .set file and a .fdt file.

A couple of weeks back, I added and updated some plugins to EEGlab. It seems like after this, the .fdt files are not automatically generated after I save a file – it only saves a .set file. And I was wondering if this is usual, or there might be some issues that I should look into?

In addition, runica also gives a different message. Before the additions/updates to the plugins, runica has been returning the same number of components as per channels (it shows a message: “Fixing rank computation inconsistency (60 vs 59) most likely because running under Linux 64-bit Matlab”).

However, runica now shows this pop-up “attempting to convert data matrix to double precision for more accurate ICA results. Data rank (59) is smaller than no. of channels (60).” and eventually computes 59 ICs. My preprocessing steps before ICA remained similar, and hence I was wondering why this message appears now?

Thanks in advance,
Gladys
