Function Documentation

ChannelInfo* read_chaninfo_ced	(	const char *	fname,
		ChannelInfo *	chans
	)

reads ChannelInfo struct from .ced file (EEGlab). Format is: One line with labels (tab-sep), followed by lines of values (tab-sep). This function reads:

• labels: "labels" "X", "Y", "Z"
  • values: char* double double double

    Parameters:

    	fname	filename
    	chans	ChannelInfo struct (large enough) or NULL (memory allocated in function)

    Returns:

    chaninfo read from file or NULL if error occured

double* read_dblp_ascii	(	const char *	fname,
		int	N,
		double *	v
	)

read 1D vector frome file

Definition at line 232 of file io.c.

double** read_dblpp_ascii	(	const char *	fname,
		int	xdim,
		int	ydim,
		double **	d
	)

read xdim x ydim matrix from ascii file with delimiter 'delim'; if NULL is passed as d, the functin allocates memory.

Definition at line 205 of file io.c.

char* read_line	(	FILE *	f,
		char *	line
	)

reads from FILE* until '
' and puts it into line. '' is added to line.

Parameters:

	f
	line	empty string (long enough), or NULL ->own memory

Returns:

NULL if error, else ptr to line

Definition at line 32 of file io.c.

Array* read_matrix_from_text

(

const char *

fname

)

Read a matrix from blank-separated file.

The format is something like this:

-0.005344   0.696318   0.005792   589.041211

...
	

Parameters:

fname

the name of the file

Returns:

the matrix
