4. Use a tiny screw driver to insert in to the power hole and lift up the screen a little bit.



 5. so that you could insert your guitar pick

7. Now, you need to take off the screws holding the top right metal and take out the top right metal
8. Use the blue tool to unplug the front plate

9.Now you've taken the broken screen off.
10. put the new one back following the reverse order of this protocol.

[imagej]how to count dots on an image

Two steps:
1. using a threshold to convert your image into binary form (positive + negative)

 Image  ▶ Adjust  ▶ Threshold. 
check "dark background"
Drag the bars so that the thresholds let the particles/dots stand out while leaving no background smears there

2. If your dots have overlapping groups, force them to separate:
Process  ▶ Binary  ▶ Watershed.

3. Analyze Particles
size: 0-infinity or leave blank
More stringent: 10-infinity 
Analyze  ▶ Analyze particles
Show:  -> Eclipse
check display results and summarize

[Solved]How to unsubscribe from Caltech Marketplace email list


"1. Click on the link at the bottom of each message (https://lists.caltech.edu/listinfo/marketplace). On the bottom of that page, there is a place to fill in your email to unsubscribe. Note: Due to Caltech's recent IT changes, you can only do this while on the Caltech network (or via VPN).

2. Using the email address that is subscribed to this list, send an email tomarketplace-leave@caltech.edu. It doesn't matter what you put in the subject line or body of the email (you can leave it blank). Use this option if you are away from Caltech and have no way of getting onto the Caltech network.

trimmomatic ILLUMINACLIP: how to specify an universal path for adaptor sequences file

A bug for ILLUMINACLIP 0.33:
They always add a prefix of locations which is the current path,  before the file name you provide. Therefore it assumes that the adaptor file is in the current folder, which is not always true.

In order to specify a universal location, you can just specify the full path and activate its full path read mode. e.g.  /usr/data/adaptors.fa

ATTENTION: never use ~ as home because it's not recognized by trimmomatic 0.33
