The "decision tree" document and appendices should guide you through the necessary stages to prepare your data for sharing.

**This is not a trivial process, but the purpose of this guide is to help you, not scare you!**

Today we are not writing a "user guide", simply determining whether the plans we have developed will work for you, if we have missed anything, or if there is anything we need to do to support you further.

**You are the ones who will be sharing and receiving credit for your data, so we want to make it easy for you!**

## Feedback on each step

## DPIA
- Jess: CTRG are happy that if your study is sponsored by them then you don't need to do a DPIA (Jess will forward and email)


### Process 3: De-identification
Personal data can not be made fully anonymous, only "de-identified" to the best of our practical ability. This process describes appropriate de-identification steps to take.

Add below any comments about each of the steps in this process.


#### Unique dicom fields
[See appedix 1](https://git.fmrib.ox.ac.uk/open-science/community/data-sharing-decision-tree/-/blob/master/docs/decision-tree-appendicies.md#dicom-scrub)
- Do you routinely or infrequently rely on any of these fields? Which would be problematic to remove? Any that should be kept for everyone?
- How would you like scrubbing to be applied? A default set of fields removed with optional extras (opt in), or all fields by default with option to keep some (opt out). At what stage of the process? Before upload to XNAT or after?
- How much date information would you like to keep (for example to handle a "product recall" scenario if a scanner fault was detected)?
- Patient size and weight are in there for the safety of the MR system. Did you know they were in there? Do we need to educate about what is sensitive in headers?
- Risk that not all scanner manufacturers have the same tags. An anonymisation tool may miss some tags.

##### Date of birth
- People wouldn't routinely go back to the dicom to get DOB (or year), unless you have acquired the data from someone else. Useful sanity check. +1
Cassandra Gould van Praag's avatar
Cassandra Gould van Praag committed
90
91
- When sharing data with industry recently, industry partner was happy to keep year of birth only
- Radiographers really like to keep full date of birth.
92
- Sharing dicoms or nifti? P1vital wanted the dicoms.
Cassandra Gould van Praag's avatar
Cassandra Gould van Praag committed
93
- **table position is used in biobank pipeline (coordinate in the scanner)**. Used in an IDP.
94
95

##### Patient sex
Cassandra Gould van Praag's avatar
Cassandra Gould van Praag committed
96
- You would expect this to be somewhere else, but good for sanity check. +1
97
98
99
100
- Same with size and weight. +1


##### Time and date
Cassandra Gould van Praag's avatar
Cassandra Gould van Praag committed
101
- acquisition time can be used to control for arousal. I would not put this in a normal database of metadata, but it is something we might come back to with a secondary hypothesis.
102
103

##### Which scanner
Cassandra Gould van Praag's avatar
Cassandra Gould van Praag committed
104
- Device serial number and institutional address. Multi centre covid study use this information...! Biobank pipeline contains a call to the pipeline to find out the address...!
105
106

##### Study description
Cassandra Gould van Praag's avatar
Cassandra Gould van Praag committed
107
- One instance with a participant which was scanned over different projects and combined to make a new one.
108
109

#### Defacing and skull stripping
Cassandra Gould van Praag's avatar
Cassandra Gould van Praag committed
110
111
- The face is usually critical for coregistration. What would be the advice; sharing the defaced structural + the coregistration info (that was derived from the complete structural)? +100. Note this is a unique
- usually get defaced images with the skull.
112
- skull gives a bit of reference (SIENA)
Cassandra Gould van Praag's avatar
Cassandra Gould van Praag committed
113
- Non-skull stripped images are used to create a reference space for creating them oxford template [Oxford-MM-1](https://git.fmrib.ox.ac.uk/cart/oxford-mm-templates); MMORF can be used to register non-skull stripped images to this template
114
115
116
117
118
119
- non-skull stripped images for olfactory bulb segmentation.


#### Quality control
- Mriqc can be run on XNAT. Would you run mriqc before your own analysis anyway?
- mriqc still being used
Cassandra Gould van Praag's avatar
Cassandra Gould van Praag committed
120
121
122
- usually done manually/visually.
- People would be happy to run a simple qc as a recommended step
- biobank by default extracts some qc measures (qc IDPs) but it doesn't exclude.
123
124
125
- **Talk to Fidel about the biobank pipeline**

127
### Process 4: Metadata

Cassandra Gould van Praag's avatar
Cassandra Gould van Praag committed
128
Your shared research data should be supported by additional metadata to make it findable, accessible, interoperable, and reusable ([FAIR](https://www.go-fair.org/fair-principles/)). This process helps you identify what metadata will be necessary to make your data FAIR, how to collate it, and how to sufficiently describe it.

Add below any comments about each of the steps in this process.

132
133
#### electrophys
- **We don't know much about electrophys metadata...***
Cassandra Gould van Praag's avatar
Cassandra Gould van Praag committed
134
- Usually you have MRI as well
135
136
- head circumference, height, weight
- which things are recorded as standard (e.g. dental wire is important to know)
Cassandra Gould van Praag's avatar

138
139
#### data dictionary
- not unfamiliar with these, expect to have in place. You learn the hard way!!

#### Image metadata
142
143
144
- dcm2niix is maybe comparable with the BIDS .json.
- downloaded data from the magnet also comes with a .json
    - what is in the non-BIDS .json which comes with a normally downloaded form the magnet nii.
Cassandra Gould van Praag's avatar
Cassandra Gould van Praag committed
145
- don't forget about the acquisition database. Could recommend that you share the entire acquisition protocol. **think about de-identifying the acquisition reports**
146
    - make sure all the radiographers positioning etc info is included (the radiographers protocol). Is this generated by default? If yes, the radiographers should upload (if no privacy concerns)

150
#### Experimental protocol
Cassandra Gould van Praag's avatar
Cassandra Gould van Praag committed
151
152
153
- Usually share the experimental script (e.g. in psychtoolbox, psychopy), along with a brief description in a README file.
- What about more detailed stuff about the session design. Some information might be on the trial registry.
- Could share a SOP for the testing, if you have that, but not everyone would have that.
154
- In the paper you would describe briefly
Cassandra Gould van Praag's avatar
Cassandra Gould van Praag committed
155
- More detail would be in the ethics. Could share the **study design section**. Don't need to share the whole document as this has other info (e.g. recruitment, researchers names).
156
157
- protocols.io. really good for wetlab experiments (has fields for doses etc.)... Not sure if it is well suited to our standard studies
- Study design section
Cassandra Gould van Praag's avatar
Cassandra Gould van Praag committed
158
159
    - wouldn't have anything specific to the participant, but it would have the different tests, questionnaires etc.
    - might also have things in there that you wouldn't want to share.
160
161
162
    - Exclusion criteria might also be useful, but not in this section.
- **How would we make sure useful things about blinding, counterbalancing etc is communicted**
Mats: In my experience , most often a file is shared (e.g. .mat file), containing some subject specific information, including counterbalancing, amounts of sessions completed etc.

This process describes how to upload your data to XNAT and make it citable. You are also asked to consider whether the standard WIN XNAT Data Usage Agreement (DUA) is appropriate for your data.

#### Upload to XNAT
- Who would you like to give internal access to your project? You, your PI and XNAT admin? Your jalapeno user group?

174
#### Data freeze
175
176
177
178
179
- some people might release in stages to give themselves a "headstart", for example some minimally preprocessed data.
- P1vital want data on a rolling basis (within 3 days of scanning)
- Maybe different versions of templates. New releases.


Cassandra Gould van Praag's avatar

180
#### Generate a DOI
181
- Mats: For the Donders Repository, a DOI is created as you create the repo - this is a placeholder that can for example be written in your manuscript, but the data will only be published after review.
Cassandra Gould van Praag's avatar
Cassandra Gould van Praag committed
182
183
184
185

#### Data usage agreement
- Which statement do you prefer about authorship on papers which re-use your data:
  1. "The data generators shall not be included as an author of publications or presentations without consent."
186
187
  2. "Neither the Donders Institute or Radboud University, nor the researchers that provide this data should be included as an author of publications or presentations if this authorship would be based solely on the use of this data." +1
Mats: People that are accessing the data have to agree they won't try to de-anonymize the data

188
189
190
191
192

#### Approve public sharing on XNAT
- How would you like to stage the approval process? Would you like the PI to approve? Email warnings / invitations? Would you like to see a review summary of the de-identification processes completed (e.g. a checklist read from the image metadata)?
- How do you think the access of external users to be managed? Should they have to create accounts? How will accounts be verified (e.g. ORCID or institutional?)? Should accounts be closed after a fixed period?
- What metrics would you like to know about how your data is accessed?

195
#### Approval of access
Cassandra Gould van Praag's avatar
Cassandra Gould van Praag committed
196
- ORCID? Institutional email?

198
199
200
201
202
203
204
205
206
207
- Log of who accesses the images
- password provided by us and renewed frequently (request from an ethics team for covid study ?OCMR)
- BHC requests (and DPUK) have to submit a request to access the data. The more things you ask for, the more you have to review (then need a review committee).


#### Citation and authorship
- this is another conversation...
