IMRO Table Anatomy

IMec ReadOut tables are simple text files that describe how to configure each readout channel on an imec probe. Each type of probe may have its own set of parameters to access that type's special features.

SpikeGLX has (or will have) a simple table editor for each probe type, but sometimes you may want to do something custom. This document shows how to write your own (*.imro) files.

You can load your own files using the Load button in the SpikeGLX table editor.

Note: When you load your own imro table file, you probably want to select default as your shank map. The default will automatically populate the shank(s) according to your imro table. You'll probably also want to select default for your channel map. The default channel map will order your graphs from the tip of the probe to the top (base) according to your imro table.

The first entry () of the table is a header indicating (probe-type, number of channels).
The meaning of the subsequent channel entries depends upon the probe type.
The table must have an entry for each readout channel, usually 384.
Entry values are space-separated.
A single linefeed '\n' terminates the file.

Channel Entries By Type

Type 0 (NP 1.0):

Channel ID,
Bank number of the connected electrode,
Reference ID index,
AP band gain,
LF band gain,
AP highpass filter applied (1=ON)

The reference ID values are {0=ext, 1=tip, [2..4]=on-shank-ref}. The on-shank ref electrodes are {192,576,960}.

Type 21 (NP 2.0, single multiplexed shank):

Channel ID,
Bank mask (logical OR of {1=bnk-0, 2=bnk-1, 4=bnk-2, 8=bnk-3}),
Reference ID index,
Electrode ID (range [0,1279])

The reference ID values are {0=ext, 1=tip, [2..5]=on-shank-ref}. The on-shank ref electrodes are {127,507,887,1251}.

Type 24 (NP 2.0, 4-shank):

Channel ID,
Shank ID,
Bank ID,
Reference ID index,
Electrode ID (range [0,1279] on each shank)

The reference ID values are {0=ext, [1..4]=tip{0,1,2,3}, [5..8]=on-shank-0, [9..12]=on-shank-1, [13..16]=on-shank-2, [17..20]=on-shank-3}. The on-shank ref electrodes of any shank are {127,511,895,1279}.

C Code: Type 0 Default

The default for a 3B type-0 probe is to select for each channel: bank=0, ref=0, APgain=500, LFgain=250, APfilter=1.

void Default3B()
{
    FILE *fo = fopen( "Default3B.imro", "w" );

    // write the header
    fprintf( fo, "(0,384)" );

    // write the rows (r)
    for( int r = 0; r < 384; ++r )
        fprintf( fo, "(%d 0 0 500 250 1)", r );

    // finish
    fprintf( fo, "\n" );
    fclose( fo );
}

C Code: Type 0 Tetrodes

Each channel will get the default reference, gain and filter settings {ref=0, APgain=500, LFgain=250, APfilter=1}.

Starting at the tip, we'll select a block of four channels by setting them to bank-0. Then we'll skip the next four channels in bank-0 by setting them to bank-1. By repeating this we will create tetrodes that cover banks zero and one.

The code will loop over sets of eight channels at a time. So there are 384/8 iterations of the loop.

void Tetrodes3B()
{
    FILE *fo = fopen( "Tetrode_1shank.imro", "w" );

    // write the header
    fprintf( fo, "(0,384)" );

    // write 8 rows (r) at a time
    for( int r = 0; r < 384/8; ++r ) {
        fprintf( fo, "(%d 0 0 500 250 1)", 8*r );
        fprintf( fo, "(%d 0 0 500 250 1)", 8*r+1 );
        fprintf( fo, "(%d 0 0 500 250 1)", 8*r+2 );
        fprintf( fo, "(%d 0 0 500 250 1)", 8*r+3 );
        fprintf( fo, "(%d 1 0 500 250 1)", 8*r+4 );
        fprintf( fo, "(%d 1 0 500 250 1)", 8*r+5 );
        fprintf( fo, "(%d 1 0 500 250 1)", 8*r+6 );
        fprintf( fo, "(%d 1 0 500 250 1)", 8*r+7 );
    }

    fprintf( fo, "\n" );
    fclose( fo );
}
