Dear Johannes,
<div class=""><br class="">
</div>
<div class="">Welcome to the community! I am not so familiar with this fileformat, but looking in the code it seems that this is a genuine bug. I am wondering whether this has ever worked at all.</div>
<div class=""><br class="">
</div>
<div class="">Long story short, in reading the header, it seems, as per line 177 in read_neuralynx_ncs, that both begrecord AND endrecord need to be defined as 0. However, in ft_read_header, line 1762, read_neuralynx_ncs is called with 1 and 0 as input arguments,
rather than (what I would expect) 0 and 0. Perhaps other people might chime in here to confirm, particularly those who are reading along and who work with this fileformat themselves, but I would say that this is incorrect.</div>
<div class=""><br class="">
</div>
<div class="">Could you try in your own code, to change the ‘1’ on line 1762 in ft_read_header into a ‘0’, and confirm that reading in of the header information then works for you?</div>
<div class=""><br class="">
</div>
<div class="">If so, then feel free to make a PR on github for this. I know it’s a silly change, which I could easily do myself, but in the spirit of ‘we’re all in it together’ I don’t want to take the opportunity away from you :). </div>
<div class=""><br class="">
</div>
<div class="">Of course I am just kidding, but also partly serious: if you make the suggested change in a pull request, then this improvement of the codebase will be forever in www-space associated with you (and who knows what the effect of this will be on
your professional career, and on the grand scheme of things). This last remark is just a gentle nudge to everybody who is reading along. Oh, and did I already raise the argument that a medical degree does not forbid you to write code?</div>
<div class=""><br class="">
</div>
<div class=""><br class="">
</div>
<div class="">Best wishes,</div>
<div class=""><br class="">
