1 == To set up your working environment: ==
2
3 1. [[Register>>url:https://ebrains.eu/register/]] for an EBRAINS account, login, and set up a [[private collab>>url:https://wiki.ebrains.eu/bin/view/Collabs/]].
4 1. Initialise the Bucket by clicking on Bucket in the navigation panel -> Create Bucket.
5 1. Give users Admin, Editor or Viewer rights by clicking** Team** in the navigation panel.
6 1. Install WebAlign, LocaliZoom, and Meshview from the EBRAINS Collaboratory App Store (see instructions below)
7
8 == How to install Collaboratory Apps ==
9
10 1. To install Collaboratory Apps, click on the + Create button (top right corner).
11 1. Give the page a Title (for example, WebAlign), select the Community App option, and click Create.
12 1. Select the App to install (for example, WebAlign), and click Save and View.
13 1. Repeat this for all the relevant Community Apps.
14 1. Navigate between the Apps in the navigation panel. File transfer between the Apps is through the Bucket.
15
16 == How to prepare your images? ==
17
18 **~1. Prepare your images before upload by naming them according this naming convention:**
19
20 The ID should be unique to the particular brain section and in the format sXXX, with XXX representing the section number. The section number should reflect the serial order and spacing of the sections (e.g., s002, s006, s010 for every 4^^th^^ section starting with section 2).
21
22 Example: tg2345_MMSH_s001.tif
23
24 - Upload the images you want to work with into the bucket of your collab using the Data proxy (press on //"Bucket"//)
25
26 **2. Image ingestion**
27
28 Two alternatives are available, the QUINT image creator app, which is automatically creating the necessary files for downstream analyses in your collab. Or, you can use the image service app which is able to create image tiles in different formats. The steps for preparing your files are described bellow:

31 === ===
32
33 === Use the "QUINT image creator" app ===
34
35 **~1. Select images to ingest**
36
37 Shift-Click on your images in order to select them and press the "create brain from selection" button. Choose a name for your serie.
38
39 The App will automatically generate the files for you. Monitor the progress under the "processing" tab and on the two dashboards on the left.
40
41 When the ingestion is finished, your serie will appear under the "Prepared Brains" tab.
42
43 Click on the "View Brain" button in order to preview your images.

50 === Use Image service app ===
51
52 **~1. Start the Image service UI from your webapp**
53
54 **2. Fill in the requested information:**
55
56 - type or paste the URL of the dataset folder containing the images. //Note!// the name of the collab supports only hyphens.
57
58 E.g. https:~/~/data-proxy.ebrains.eu/api/v1/buckets/name-of-my-collab
59
60 - you can filter the data using RegEx expressions. E.g. name_of_the_data_file.*\.jpg$ (for filtering jpeg files only). Or e.g hbp-00173_262_1366_1827.*\.tif$ for tiff files.
61
62 - If your URL is valid, you will see the list of files by pressing "yes". Paste the name of the file you want to select. You can go back to the previous step  by pressing "back"
63
64 - Or use a prefix: E.g. https:~/~/data-proxy.ebrains.eu/api/v1/buckets/name-of-my-collab?prefix=name_of_the_data_folder
65
66 - allow the image service to access your bucket
67
68 [[image:Skjermbilde 2022-02-08 103443.png||height="199" width="500"]]
69
70 - Store your results: Choose "create a new collab" where your ingested chunks will be stored in the bucket. This option is preferred in order not to overload the Bucket of your current  collab. Give a name to your Bucket as well as a name for the  collab (bucket slug) (see this illustration for more info)
71
72 [[image:create collab.png||height="427" width="900"]]
73
74 - Customize your ingestion:
75
76 - give a name to your ingestion in the "description of ingestion" field.
77
78 **3. For obtaining chunks in DZI format  (compatible with WebAlign),** choose "2D" and "not stack of Images".
79
80 **4. Click //"preview"// in order to preview your task**

156 == **How to use WebAlign** ==
157
158 WebAlign is an online tool for spatial registration of histological section images from rodent brains to reference 3D atlases.  Different experimental datasets registered to the same reference atlas allows you to spatially integrate, analyse and navigate these datasets within a standardised coordinate system. The output of WebAlign can be used for analysis in the online QUINT workflow.

161
162 The view can be magnified using the 4-arrow "X" symbol in the top-right corner.
163
164 === Opening a sample dataset ===
165
166 Demo dataset is loaded using the file: **demo_mouse_data_start**
167
168 You can see the result of a finished anchoring by choosing the file: **demo_mouse_data**
169
170 === Opening a private dataset ===
171
172 After you have uploaded your images to the bucket and ingested your images with the Image service, this has generated DZI chunks. These DZI files are used by WebAlign.
173
174 ~1. Start a new registration by pressing "create new series", the UI will ask you for the name of the collab where DZI chunks are stored. E.g. my-collab-name
175
176 2. WebAlign will search for DZI files and list those found.
177
178 3. Enter a name for the descriptor json file which will be created and will contain your anchoring information.
179
180 4. Choose the target 3D reference atlas (WHSv3 for Rat and CCFv3_2017 for Mouse).
181
182 5. Press //"create"//. The main window will now display WebAlign. This step can take some time.
183
184 === Registration instructions ===
185
186 **Short keys**
187
188 |=To do this|=Press|=Description
189 |Place marker|Space bar|Markers are the anchor points of most transformations (stretch and rotate).
190 |Remove marker|Esc|Removes a previously placed marker.
191 |Horizontal stretch from marker |Left/Right arrow keys|Marker becomes a vertical line, and mouse drag horizontally resizes the cut.
192 |Vertical stretch from marker |Up/Down arrow keys|Marker becomes a horizontal line, and mouse drag vertically resizes the cut
193 |Rotate around marker|PgUp/PgDown|Marker becomes a cross with a surrounding arc, and mouse drag rotates the cut.
194 |In plane adjust |Click + drag|If there is no marker, or the marker is a cross, mouse drag slides the cut in its plane (translation).
195
196 **Start the registration**
197
198 The main window shows the selected image with the atlas overlay.
199
200 -If necessary, change the atlas from coronal view to sagittal or horizontal view (see Navigation panel below)
201
202 ~1. Move the atlas to the approximate position of your section using the yellow dots in the three small windows from the navigation panel.
203
204 2. Start anchoring by placing a marker with the //"Space bar//" , it is initially a cross, and it is the fix point of (most) transformations. The "//Escape key//" can be used to remove the marker.
205
206 3. The main window supports mouse drag in multiple modes in order to stretch the atlas and find the correct position.
207
208 -If there is no marker, or the marker is a cross, mouse drag slides the cut in its plane (translation).
209
210 -Keyboard controls to modify mouse drag (they also place the marker if it's not placed already):
211
212 -Left/Right arrow keys: marker becomes a vertical line, and mouse drag horizontally resizes the cut
213
214 -Up/Down arrow keys: marker becomes a horizontal line, and mouse drag vertically resizes the cut
215
216 -PgUp/PgDown keys: marker becomes a cross with a surrounding arc, and mouse drag rotates the cut. This may look weird because the cut remains being a rectangle, and when  the horizontal and vertical physical resolutions (like pixels/mm) of the image do not match, atlas cut will appear stretching/shrinking with the rotation.
217
218 After each transformation step, marker resets to a cross (translation mode).
219
220 //Note!// The panel can be resized towards the left (common border with Control Panel) and towards the bottom (common border with Filmstrip).
221
222 4. Save the position by pressing //"Store". //The registration is copied to the remaining slides to help with scaling (visible also in the filmstrip)
223
224 5. Go through all sections and refine position and cutting angles.
225
226 //Note!// When jumping from one section to the other, wait a few seconds for the image to load
227
228 //Note!// The "restore" button allows you to go back to the saved position if necessary
229
230 6. Save your results in the descriptor file (json) by pressing "Save to bucket".
231
232 7. When the registration is finished, you can export your descriptor files ( .flat files used for analysis in the QUINT workflow) by pressing //"export overlays".//
233
234 **Control panel:**
235
236 |=Button|=Function
237 |Store |Store the current alignment and propagate to unaligned sections (**Note** this does not save the series to your bucket)
238 |Restore |Reset the current alignment to the last stored position
239 |Clear |Reset the current alignment to the default position
240 |Overlay Slider |Opacity of the atlas overlay, when fully opaque, it becomes an outline
241 |Overlay color |The outline color
242 |Filmstrip slider and color|The above settings, applied to the filmstrip
243 |Save to bucket|Save the series to your bucket (and overwrite the existing file)
244 |Export overlays|Generates a series of .flat files (for Nutil or similar utility), and stores them into a .zip file in the bucket (re-using the name of the series descriptor, e.g. series13.json will export series13.zip)
245
246
247 The right border of the control panel can be dragged horizontally, allowing to resize the panel and the main view
248
249 **Filmstrip:**
250
251 Drag horizontally to see series, click on a section in order to load it into the main view The top border of the filmstrip can be dragged vertically, allowing to resize the panel and the main view
252
253 **Navigation panel:**
254
255 Shows the three standard planes centered around the midpoint of the current alignment visible in the main view.
256
257 The rectangle of the current cut is projected on each standard plane as a yellow line/rectangle/parallelogram. A small yellow circle represents the midpoint of the projection.
258
259 Drag the midpoint around to move the cut.
260
261 Drag anywhere else to rotate the cut (inside the given standard plane, around the midpoint)
