Save Tab

Use this tab to:

• Save annotation notes into your metadata files.
• Set where to save and what to name the output data files.
• Check the available disk space, hence, maximum possible recording time.

Run Name and Run Continuation

You can set the name for your run either in this tab’s Run name box or in the run toolbar at the top of the Graphs window. In the Graphs window you must first pause writing via the optional Enable/Disable Recording button as described here.

Both of these inputs accept either an undecorated base-name for a run, or a decorated name of the form run-name_gN_tM. The decorated form tells SpikeGLX you wish to continue writing additional files into an existing run, starting at the specified g/t indices. This is very useful if a run had to be interrupted to repair a problem.

Note too, that you can change to a different run name without stopping the run. Use the Graphs window Disable button to pause writing, then type in a new undecorated name (no g/t indices). This will be treated as a request for a brand new run name that will start at _g0_t0.

Unique Name Rules

If the run name is undecorated, the provided base-name must be unused in all of the current Data Directories.

If the name is decorated, then those indices must be unused. That is, run-name_gN_tM must not exist in any of the current Data Directories.

Folder per probe

Create a run subfolder for each probe.

Suppose you have two 2.0 probes {0,1} in myrun…

Box unchecked, flat file organization in run folder:

data_dir/
    myrun_g0/
        myrun_g0_t0.imec0.ap.bin
        myrun_g0_t0.imec0.ap.meta
        myrun_g0_t0.imec1.ap.bin
        myrun_g0_t0.imec1.ap.meta
        // other non-probe stream files

Box checked, probe subfolders:

data_dir/
    myrun_g0/
        myrun_g0_imec0/
            myrun_g0_t0.imec0.ap.bin
            myrun_g0_t0.imec0.ap.meta
        myrun_g0_imec1/
            myrun_g0_t0.imec1.ap.bin
            myrun_g0_t0.imec1.ap.meta
        // other non-probe stream files

Separate shanks

Write separate bin/meta for each shank of your 4-shank probes…

• This only affects 4-shank probes.
• Each 4-shank probe has an original probe-ip.
• Multidisk directory selection is based on original ip.
• Folder per probe option is based on original ip.
• The filename for {ip,shank-s} is: 1000 + 10*ip + s.
• Only non-empty files are written.
• Adjusted metadata reflect intersection of {original saved chans, chans on that shank}.
• The original probe-ip meta file is also written as a settings record.

Suppose you have two 2.0 probes {0,1} in myrun, such that probe-0 is a single shank probe and probe-1 is 4-shank…

• Folder per probe: checked.
• Separate shanks: checked.
