Dear
Hope you are doing well
I have some questions to ask about the sensor dataset please respond to them
1: sensor part I and II what are their sizes? Second due to their size can we download some part of it?
2: Levodopa dream challenge and mpower what are these dataset sizes?
The final question is the same can we download the accelerometer gyroscope and magnetometer data in which we are interested? If yes downloadable then plz share the procedure of it in detail.
Also breif information about datasets and thier label and no of classes in them
Thank you
Created by Syed Muhammad Zaid zaid_icp.1 Thank you for your response it is very helpful.
Now I limit the size of downloadable files, it gives the message "files downloading 0 Cached locally".
Dear how I can save them locally on my PC.
Waiting for your response.
> 1: sensor part I and II what are their sizes? Second due to their size can we download some part of it?
[Sensor Data - Part I](syn20681931) is 68.5 GB in size and [Sensor Data - Part II](syn20681932) is 70.7 GB in size. You can download part of the data by including your filtering criteria in the query.
```
sensor_measurements_query = syn.tableQuery("SELECT * FROM syn20681931 LIMIT 10")
sensor_measurements_paths = syn.downloadTableColumns(sensor_measurements_query, "data_file_handle_id") # download data
# etc
```

Most of the size of the MJFF Levodopa Response Study data comes from the sensor data -- so approximately 140 GB. I don't know the size of the public mPower dataset and I don't have access to that data. Could you ask this question on the mPower discussion forum so that more people can benefit from your question?
> The final question is the same can we download the accelerometer gyroscope and magnetometer data in which we are interested? If yes downloadable then plz share the procedure of it in detail.
The data is provided as-is. You can use table queries to filter data which you want to download ([Here are some examples](http://rest-docs.synapse.org/rest/org/sagebionetworks/repo/web/controller/TableExamples.html)). Only accelerometer data is provided as part of this study.
> Also breif information about datasets and thier label and no of classes in them.
You will probably want to download the data yourself and look at the class breakdown by `task_code` and `body_segment` as well.
