GGIR can't read .gt3x files that it opened once

[rsob...@gmail.com]

Hi all, 

I recently have conducted an analysis in a .gt3x file that went normal. I installed the new version R-studio (not R) and it simply stopped reading the same file. 

The error is: Loading chunk: 1Error in as.POSIXlt.numeric(x) : 'origin' must be supplied

I am running GGIR version: 3.1.0 and checked the gt3x file as per other forum discussion: 

Sampling Rate: 30Hz
Firmware Version: 1.9.2

Serial Number Prefix: MOS 

R comes back with the following:

 Part 1
Checking that user has read access permission for all files in data directory: Yes
1
File name: Dado Modelo Capacitação Acelerometria.gt3x
P1 file 1

Investigate calibration of the sensors with function g.calibrate:

Extract signal features (metrics) with the g.getmeta function:

Loading chunk: 1Error in as.POSIXlt.numeric(x) : 'origin' must be supplied

Can anybody please help me with the issue?

Many thanks in advance

This user experienced a similar error and it turned out to be something with the version of R: https://groups.google.com/g/rpackageggir/c/V3GqrSfiZcg/m/nZ3IxMlNAwAJ

However, it sounds like you've had success running this .gt3x file through GGIR before on your version of R - the only thing that changed is RStudio. Even still, what version of R are you using and on what operating system?

I had success just now running a .gt3x file through GGIR 3.1-1 on R versions 4.3.3 and 4.1.1 (w/ RStudio 2024.04.2+764 "Chocolate Cosmos").

Best of luck!

Many thanks for the quick reply Michael. 

I have now updated all my softwares around here and all is working fine.
