Raw Data Downloading

[shawaf92]

Hi ,

There's no issue here just need to understand more how is raw data downloading is working I made many test sometimes it's very small size like 25 mb and sometimes it's 180 mb Does it work per cine ?( I mean if i run capture cine and then download raw data will it download the raw data for this cine only or all the raw data for past cines )

Thanks

yes, when you turn data on, it buffers on the probe device. when you then make a single capture, it will just download the corresponding frame, and when making a cine capture, it will download the last X seconds of data, assuming that it is still buffered - note that buffer is of fixed length on the probe device, so scrolling back in the cine and downloading may not yield any raw data if it has been overwritten

okay , how much time it still buffered after taking a cine ? and assuming the current scenario for taking 4 cines from 3rd party app : 1- Capture Cine 1 -> Download Raw Data -> Raw_Data1.tar
2- Capture Cine 2 -> Download Raw Data -> Raw_Data2.tar 3- Capture Cine 3 -> Download Raw Data -> Raw_Data3.tar
4- Capture Cine 4 -> Download Raw Data -> Raw_Data4.tar

Will that work (having raw data tar file for every cine) or Raw Data 2 will have raw data for cine 1 and 2 and so on . Cause i saw that only Raw_Data1.tar that has normal size and then next ones getting bigger .

buffer is fixed size, so not time dependent, depends on scan settings buffering/downloading raw data works as follows:

• scan
• freeze
• select frame(s)
• capture (cine 1)
• unfreeze
• scan
• freeze
• select frame(s)
• capture (cine 2) ...

So following on that I have been trying this order to download the data But there are many stability problems and result usually don't have the correct data

I was doing the following from 3rd party app depending on mobile API

• scan (capture cine) then (freeze) then (download row data)
  But always download is interrupted by many things -- Port is closed (Write of 96 bytes failed with error: Bad file descriptor) -- Receive empty raw data --(Wrong size returned when trying to read 65535 bytes at offset 65535 from block raw data (got 0 bytes)) And in case of case succeded to download data, it returns with one 1:3 of supposed +50 mb

So How can I avoid these exceptions, what's the best scenario?

Any help with these issues ?

[clariusk]

we'll have a team member take a look, and try and reproduce, thanks for reporting.

[shawaf92]

Hi Kris , were the team able to reporduce these issues ? should I expect any fix for it soon ?

[clariusk]

there have new stable software in pilot (8.4.2 on Android and iOS), and suggest trying this. we'll have some updated api docs as well to go along - app store release likely later this month

Hello, I just checked the status of the next Pilot version: it is still undergoing internal testing to ensure stability. It shall be available soon, sorry for the delay.
