    Dear all,
    i’m using Lead-DBS, i usually work on CT scan and I’ve run into difficulties with the recostruction step. I tried to use the default method PaCER, but i got this error

    Warning: PaCER failed with the following error:
    In ea_autocoord (line 270)
    In ea_run (line 96)
    In lead_dbs>run_button_Callback (line 187)
    In gui_mainfcn (line 95)
    In lead_dbs (line 43)
    In matlab.graphics.internal.figfile.FigFile/read>@(hObject,eventdata)lead_dbs(‘run_button_Callback’,hObject,eventdata,guidata(hObject))
    Identifier:
    Message: PaCER returned a different number of electrodes than expected by LeadDBS! In most cases this indicates an error in PaCER preprocessing (brain mask estimation) due to untypical CT data. Please provide a brain mask to PaCER in this case using the mask parameter.
    In: C:\Users\BIOING\Desktop\STUDI\lead\ea_runpacer.m
    Method: ea_runpacer
    Line: 17
    Please check your input data carefully.

    So lead-dbs revert to “Trac/Core” algorithm and here i got an other error:
    Error using ea_reconstruct_trajectory (line 282)
    Mask out of bounds! Must have lost trajectory…
    Please try a different ‘Mask window size’ or try manual mode by setting ‘Entrypoint for Target’ to
    ‘Manual’.
    Error while evaluating UIControl Callback.

    What’s wrong? I would like to use PaCER even because in your papar is written that it requires very little to no manual refinament.
    Could somebody help me?
    Thanks in advace.
    Regards,
    Arianna

    Dear Andy,
    can you please redirect the link? Because nothing appears to me.
    Thanks, Arianna
