Why doe Resample waveforms (continous).vi have missing data

I am using the Resample Waveforms (continous).vi to resample waveforms at a slower rate than the acquisition is taking place. I am doing this because I am using an NI-9237, which has a minimum sampling rate of 1612.9 Hz. I am acquiring from up to 12 channels of AI and resampling the array of waveforms. When I save the output of the resampling VI to a file, some of the channels have missing data for a given timepoint and sometmes the timepoint will be off. I have removed the Reasmple VI and I do not see this problem.
I have attached a screenshot of my VI and of the saved data file (time is leftmost column, one column for each channel).

Amit,
I ran some more tests. I should have mentioned I was using a simulated device (as I do not have the actual hardware yet) to troubleshoot my application. I happen to have another peice of "real" hardware that I tried and I cannot seem to duplicae the issue with it. I need to wait for my actual cDAQ to arrive before I can be sure, but this seems to be the problem. It still doesn't make sense to me since using the simulated device without the Resmaple VI produces accurate "simulated timepoints. It's when I introduce the Resample that I have problems.
Thanks
Dan

Why doe the iphone 5 not have the show my caller id

Why does the new Iphone 5 not have the show my caller ID?

Hey, thanks for the response!
I'm positive I was using the Netflix app on the iPhone and ps3, when it stopped working I tried looking it up, and ran into these website: http://www.engadget.com/2012/09/25/netflix-ios-android-ps3-second-screen-remote- control/
http://m.tuaw.com/2012/09/26/netflix-for-ios-has-second-screen-remote-control-fo r-ps3/
I read the two apps are able to connect because they are under the same wi-fi connection, but I haven't changed wireless modems, or any settings on the iPhone and ps3!

Why do my Adobe cc files have no date?

I organise my files in folders and have the newest files at the top of the list. Lately, files I have created or old files I have worked on are under the section 'No Date' so at the bottom of the folder list. This is a real pain when you have multiple copies and you want to reopen or access the latest version or file you've created!
Does anyone have any ideas how to rectify this? It happens in all programmes and is really annoying - as are all the bugs now in CC!!!!

NO MATTER WHAT VERSION OF WINDOWS YOU'RE USING:
Right click one of the PDFs with the Word icon.
Select "Properties"
Where it says "Opens With" there is a button to change it from Word to Adobe Reader, which should be in the list of available programs that pops up.
Choose Reader, and click APPLY before clicking OK.
That will change ALL PDFs to Reader as the default application.

HT4850 I seemed to have missed the whole ordeal of keeping my 10.4.11 os x powerpc up to date. Are these suggestions still viable as I have been getting all sorts of console errors which now seem to lead me to this researched destination?

I seemed to have missed the whole ordeal of keeping my 10.4.11 os x powerpc up to date. Are these suggestions still viable as I have been getting all sorts of console errors which now seem to lead me to this researched destination? The suggestions involve putting "sudo" in Terminal Application and I am assuming that with all the console errors now being generated by my "permissions fixer" that this might be the reason...missed the class and updates as I never had problems like these before and the technology is changing. Have a whole list of console errors if someone is willing to help as I also think I have hit the motherload as to the reasons why?!

Why the images have missed their frame stroke, once online?

I am working on my new website on iweb 09, and published a test, it looks very nice.
The only thing I don´t understand is why the images have missed their frame stroke, once online.
What´s wrong, any idea?
On iWeb, Inspector/Graphic/Stroke/Picture Frame

It appears that the Scrips folder for you site has not been uploaded or not uploaded fully. There are two files, iWebImage.js and iWebSite.js. Try the following:
1 - do a File->Publish Entire Site and see if the site works as intended. You may have to do a refresh on the pages a couple of times.
2 - next, in needed, publish your site to a folder on your hard drive. Mount your iDisk and go to the iDisk/Web/Sites/arkimo folder. Drag the two files above from the Scripts folder on your computer into the Scripts folder on the iDisk Then try the site again.
Part of the problem is the server, some files not loading the first time, and part is the missing js files in the Scripts folder.

Resample Waveforms (single shot) VI. Bug in normalized bandwidth?

I resample signal from 400 kHz to 44.1 kHz. I set normalized bandwidth = 0.0001 and listen my signal with great quality at 60 dB rejection.
If 0.5 <= normalized bandwidth <= inf, I listen bad sound. And why I have no error at normalized bandwidth > 1?
LabView 2013 32bit.

Yes, I demodulate signal from FM radiostation. I/Q samples from USRP have Fs = 400 kHz, after I resample signal to 44100 Hz. Resample is needed to antialiasing filter.
I want to listen mono-signal, one has Fmax = 15 kHz, i.e. 15/44.1 = 0.34. I set normalized bandwidth = 0.34 in Resample Waveforms and rejection = 60 dB. Am I right? These are the antialising filter parameters? If I set bandwidth = 1e-6, I listen same good signal. How is this possible at this rejection?
In the other case I resample signal to 96 kHz. Bandwidth = 15/96 = 0.15, I listen good signal. At bandwidth = 0.47 I listen good signal (it's strangely, because Fm = 0.47*96 = 45.2 kHz). But if I set bandwidth >= 0.49, I listen bad signal (only jerks).
Bandwidth = 0.47, good sinal
Bandwidth = 0.49, bad signal
I think that the normalized bandwidth can take values from 0 to 1 (bandwidth/Fs_new). But if I set normalized bandwidth > 1, I have no error. It's very strangely.

HT202020 Why are certain videos that I have taken with my iPhone 4 not supported by Aperture.

Why are certain videos that I have taken with my iPhone not supported by Aperture? That's weird. I expect that since both iPhone and Aperture are Apple products, file support should be seamless between the two.
Also, iPhone 4 does not appear as Camera Model in the metadata of the unsupported video file in Aperture . But other videos I have taken with the same iPhone 4 appear in Aperture and the Camera Model appears correctly. Why is that?

Have you done some cleaning and cleared caches on your Mac? Maybe the com.apple.xpchelper.cache file is missing. Check the folder /System/Library/Caches/
Re: Import video to Aperture library on Mountain Lion https://discussions.apple.com/message/19304702#19304702
If this file should be missing, you need to restore it from a backup or reinstall it by reinstalling your system.

Why do the Apple default apps have so many issues?

With my upgrade from my trusty but dying iPhone 4s to a shiny new iPhone 6, the additional screen real estate makes me want to do a whole lot more. Things that I would previously never have dreamed of doing now approach the realm of the possible. With that, the limitations of Apple’s own apps also come to light. What follows is a wish list of sorts, stuff that I wish Apple would “get right” so that I don’t need to find separate workarounds.
Music
Synchronization. As my music collection grew, sync issues and weird behavior went from being a once-in-a-product-lifetime anomaly to a regular occurrence. Sometimes, a significant portion of my music collection is missing on my iPhone. Other times, the album art is only partially there. Yet other times, I search for an album by name and see only a subset of tracks but then search by artist and all the tracks are there. Or the playlist label is there but some or all of the songs aren’t listed. It’s all perfect in iTunes, but not on my phone. I have disabled sync’ing over WiFi and now do so only over a wired connection to my iMac. I have changed USB ports. I have changed Lightning cables. Nothing seems to work.
Search. The app always displays search results in the same way, regardless of which context I’m in. So irrespective of whether I’m in the Artists view or the Album view, results are displayed first by Artist, then by Album, then by Song. If I’m in the Album view, I want it by Album first! If I’m in the Playlists view, I want to search the titles of my playlists. Simple things.
Alphabetical Search. From A, I scroll, scroll, scroll, and then it does P to # just beautifully. What happened to B to O?
Genres view. This is a mess. The same genre shows up multiple times and, inexplicably, under different letters of the alphabet. Did this even go through QA?
Notes
Groups. I can only add a new group via my iMac’s desktop app (and possibly through a browser via iCloud.com, though I haven’t tried that). Why is this not possible in the iOS app?
Synchronization. I have a whole bunch of notes in my iMac’s Notes app that do not show up on my iPhone. They did once, and then poof, gone. They’re all visible on iCloud.com, though for some reason the embedded photos are not. This lack of reliability forces me to use Evernote, which really shouldn’t be necessary. Sync should just work.
Contacts
Groups. I want to be able to create, edit and delete groups in the iOS app. I want to be able to add a new contact to a group without first having to Hide All Contacts, select the group I want, create an entry, flip over to Messages, then finally add the contact’s number from there to the new entry. Why is this so painful?
Related Names. I love this, but why isn’t it smart? For example, if I add someone’s husband who is already listed in my contacts, then why doesn’t the wife automatically show up in the entry of that husband?
Calendar
Show All Notes. This does not, in fact, show all notes. It seems to cut off after a certain number of characters. If someone sets up a meeting invite in Outlook and there are oodles of intro text in the calendar entry’s body before the dial-in details are listed, then I cannot get to those details from my iPhone. I have to boot up my laptop and fire up Outlook, by which point I have missed half the meeting.
Inbox. Some stuff from Outlook/Exchange shows up here. Other stuff does not. If I take an action such as to accept or to decline a meeting, this doesn’t clean up the invite from my Mail Inbox as it would in Outlook. Frustrating.
No doubt, I have forgotten to list a few things. Apple, I know you pride yourself in the integration of hardware and software. Why, then, are the basics missing? Please get them sorted.

Why is my Crop Guide Overlay dropdown missing?

Can someone explaing to me why my Crop Guide Overlay dropdown is missing?
Adobe Photoshop CS4.
I'm sorry, I'm very frustrated. There used to be a day when you could click on help and it would bring up help topics on the product you purchased. Now, I get a website with CS5, CS6 and whatever else. I can't find the answer to my problem, I've been searching for too long now so I'm posting here.
Thank you in advance.

What Crop Guide Overlay are you expecting?
Something you've seen in a later version of Photoshop, perhaps?
Later versions of Photoshop offer more things, like a Rule of Thirds overlay. As far as I remember, Photoshop CS4 simply didn't have that, and showed you just what you're seeing in the screen grab you posted..
You could emulate a rule of thirds grid, I suppose, by creating both Horizontal and Vertical guides at 33% and 67%. But they will not move as you change the crop dimensions.
