Error received using Nirslab2017.6 to compute hemodynamic states

Eunice Chen — Tue, 04 Sep 2018 21:08:49 GMT

Hi, I run into this error when I have finished preprocessing my fnirs data in Nirslab 2017 and try to
'compute' hemodynamic states. I noticed this on the standalone and matlab platformed versions.

I was wondering if other folk have run into this before and if so, how they have addressed this.
Regards,
E

RE: NIRSlab for mac

Hi,

I agree with the reply from Chen Rui. The executable version(s) of nirsLAB are for Windows platforms only. The MATLAB p-codes, however, work for Mac and Linux in addition to Windows.

NIRS_SPM error when loading data

Geoff Green — Mon, 12 Mar 2018 15:53:57 GMT

Hi,

Previously, I have tried using this toolbox with Matlab 2017b, but was instructed to try 2014a, as mathworks changed the way graphics are used in matlab after 2014a. So, I tried loading the data through Matlab 2014a, but it still gave me the same exact error message as before in 2017b version with only the second from the last line being different (highlighted in red). This error occurs when I try to load data using the GUI. Specifically, when I try to load the data, I check the "stand alone" box, click the "spatial registration button, check the "with 3D digitizer" box, and proceed to load the "origin/others" files. I load the "origin" file with no problem, however, when I go to load the "others" file, the program won't allow me to load it and this error message appears:
_____________________________________________________________________

Undefined function or variable "str_optd".

Error in NIRS_Registration_Standalone>push_real_optode_channel_Callback (line 729)

nirsLAB 2016/2017 GUI window error

Geoff Green — Wed, 01 Nov 2017 23:17:03 GMT

Hello Dr. Graber,

I have been having issues downloading the later versions of nirsLAB. I want to update it because nirsLAB 2016/2017 both have the ability to implement FDR (false discovery rate) through the AR(n) data analysis option.
There is no download for the 2016/2017 standalone versions, so I tried the p-codes. However, when I typed 'nirslab' in the matlab command window, this image attached is what pops up, not allowing me to properly use the data analysis software at all.
Please advise for this situation.

Best,

Dear Don and Sébastien,
I'm sorry for getting back to you so late. The p-codes are now also available.

Kind regards,

Any update on this one?

Thank you,

I noticed that the current version of nirsLAB is available as a Windows executable installer. For those of us using Macs, is there a plan to post the p-code so that we can run the software as we have been able to with previous releases?

RE: "Out of memory" error

Harry Graber — Tue, 10 Jan 2017 5:32:47 GMT

Hi Grace,

      When nirsLAB reports "Out of memory," that always means that it doesn't have enough RAM for the operation you are trying to perform. It is not about the amount of free disk space, so freeing up 100 Gb is not necessary and not going to have any effect.

      What kind of processor and operating system does your computer have? If it is a 64-bit machine, then you can and should use the 64-bit executable. That is the single most important and helpful thing you can do to increase the amount of memory that is actually available to nirsLAB.

      Please also indicate which user-specifiable options you had selected when you tried to do the SPM1 computation. Some of them can be memory hogs. The pre-whitening option is an example.

      For follow-up (and for future technical-support requests), please send e-mail to support@nirx.net. That will ensure that you get a prompt reply. (This request was spotted less than a day after you posted it, but we can't guarantee that this will always be the case.)

Harry
