ActiPass File Error – Sample Rate Outside Expected Range

[loris-lee]

Hi,

I am encountering a file error in ActiPass when trying to process .datx files from ActivPAL 3 devices. The software fails to open certain files, displaying an error message stating that the sample rate is outside the expected range.

Issue Description:
When processing .datx files from ActivPAL 3 devices, ActiPass indicates that some files cannot be processed.

When attempting to open files from IndividualOut, I receive the following error:

FileLoad: Error reading file: The sample rate is outside the excepted range in file:
\uol.le.ac.uk\root\staff\home\j\jl933\Desktop Files\File Errors\PL10090-AP1234635 07Feb14 10-00am for3d 1h 44m.datx
Please report this to the developers at:
https://github.com/R-Broadley/activpal_utils-matlab/issues.

All files come from ActivPAL 3 devices, but not all are processing correctly.

I have processed 2,079 files in total across different batches, but 11 files failed. These failed files can be processed using other accelerometer software.

I attempted to process all failed files together in ActiPass, but they failed again.

Logs & Attachments:
I have attached the ActiPASS_BatchSettings.txt and ActiPASS_BatchLog.txt files from the 11 failed files processed in ActiPass:

ActiPASS_BatchSettings.txt from the BatchOut folder.
ActiPASS_BatchSettings.txt
ActiPASS_BatchLog.txt (trimmed to show only the relevant errors).
ActiPASS_BatchLog.txt

Has anyone else encountered this issue? Any suggestions on how to resolve it?

Thanks

Hi,
Most probably the files are actually from ActivPAL 4 devices. Convert them to CSV and process them.

Hi Pasan,

Thank you for your reply.

I confirm that all the files are from ActivPAL 3. I converted the failed files into CSV and attempted to process them in ActiPass, but the issue persists. The IndividualOut file displays the following error message:

FileLoad: Error reading file: Error loading ActivPAL CSV file: Dot indexing is not supported for variables of this type.

Do you have any suggestions on how to resolve this?

1. Can you show the steps you did to convert DATX file to CSV? Most probably you have not converted to the correct CSV format. Did you use the sensor data export option of PALBatch or PAL Analysis? See PalBATCH algorithm #87 (comment) for correct settings.

2. Can you list the first 10 lines of the converted CSV file? You can do it via Windows PowerShell if you are familiar with it. replace filename with full path to exported CSV file in the command below. We should see lines like the screenshot below.

Get-Content *filename* -Head 10

4. Anyway the error you describe normally happens when one tries to load AP4 .datx file with ActiPASS. Can you upload what PALAnalysis show about one of these specific files in its "File Deatails" like seen below.
