QUESTION
I'm in a bit unusual situation. There are seven different proteins stored in a single file according to their residues names. Each protein has different sequence length. Now I need to calculate the center of mass of each protein and generate a time series data.I know how to do with a single protein, but do not with multiple protein system. For single protein I can do something like this:
...ANSWER
Answered 2022-Mar-01 at 15:49I would load the system from the TPR file to maintain the bond information. Then MDAnalysis can determine fragments (namely, your proteins). Then loop over the fragments to determine the COM time series:

I'm trying to write some abstractions in some Spark Scala code, but running into some issues when using objects. I'm using Spark's Encoder which is used to convert case classes to database schema's here as an example, but I think this question goes for any context bound.
Here is a minimal code example of what I'm trying to do:

Answered 2022-Feb-10 at 14:17Your first error almost gives you the solution, you have to import spark.implicits._ for Product types.

QUESTION
I'm trying to update a piece of old code (a menu builder class). I've updated everything else but I'm stuck at a line that uses the each() function. I did read some of the previous threads but this particular instance is too complex for me to figure out how to change. Here it is:
...ANSWER
Answered 2022-Jan-24 at 20:58As a general rule, if you need to move away from each($ar) you can usually use [key($ar),current($ar)] as a drop in replacement but then you need to move the pointer within the loop. You usually just need to call next($ar) within the loop and break once you run out of reading room such as breaking when the key is null. Then just make sure the array becomes set to false when it runs out of room.
This type of approach can get ugly very quickly though due to the extra code...
So without really paying much attention to your code, after this update, your revised code would like look:

I'm a JS, phaser3 and Socket.io newbie and I really want to learn.
Code Context:
- Phaser3
- Socket.io
- Loading state of game room before socket connects
- Generating the NPC's and players
- fails when there's an attempt to access NPC's (mass) sprite in the same callback it was created
Issue:
- Cannot access the sprite property, and in general seems like the object wasn't created in the first place
I have the socket listening in Phaser3's "create()" function for "universeState" after it has connected to the socket server. index.js:
...ANSWER
Answered 2022-Jan-22 at 18:04The reason why you cant access the property is "easy", it's because the this.state.state.mass object is empty.

QUESTION
I have some working code using MDAnalysis that saves the residues center of mass time series in an array, but I wonder if there is a more Pythonic or overall efficient/fast way (comprehensions, array operations...) to do it.
...ANSWER
Answered 2022-Jan-19 at 14:57There are a couple of changes you could make to your code:
- select your protein atoms outside of the for loop, rather than on each iteration
- vectorise the center of mass calculation over residues by passing the
compound='residues'argument to thecenter_of_massmethod - use the
ag.n_residuesandu.trajectory.n_framesattributes
Here's an update to your code that uses these suggestions:
QUESTION
I've been doing a lot of reading on how different people implement socket.io in their multiplayer games so that I can use it in mine. Granted, I'm a noob with the networking layer for this and I desperately need to learn.
Code Context:
-Using Phaser3
-Multiplayer game
-Load all existing players
-Broadcast player joined
-Update player position <--- My issue derives from here
Issue:
-Seems to only update position of the newest socket that joins and broadcasts it
-Might not be important but incoming socket.id seems to replace the last socket.id it was set to as id, and I think this since the argument for "run this if incoming socket is not equal to your socket" does not run
-In general, not updating the state of other players in game (not moving the others)

QUESTION
I have a quiz and on the final round, I would like it to end if it gets an incorrect value
I have an if loop, but I would like my final else values to have a go to line line number code as it is a long code. In order to use this function, how could I view line numbers (I use Portable Python Scripter).
ANSWER
Answered 2021-Dec-12 at 20:25Using loops and functions can help you make this code quite a bit shorter and eliminate a lot of the need for copy+pasted if/else. Here's a quick rewrite of the initial quiz section with the outline of a main() function to give you the idea:

I have a pretty basic construction of loops in mind for lean. I construct a class for magmata, a class for quasigroups (cancellative magmata), and a class for unital magmata. From there a loop is just something that is both a quasigroup and a unital magma.
In Haskell this would look like

QUESTION
I'm building a Shiny app in which I'm trying to implement a checkbox type filter.
In the input called phones There is one option titled Yes. When Yes is ticked off, it will limit it to anyone in df whose field for phone IS NOT NA. When it's not checked off, it will include all fields under phone regardless if its NA or not.
The error I get:
Warning: Error in : Problem with `filter()` input `..1`. ℹ Input `..1` is `&...`. x `input$phones == "Yes" ~ !is.na(temp_data$phone)`, `TRUE ~ !is.na(temp_data$phone) & is.na(temp_data$phone)` must be length 0 or one, not 10000
