Beautiful images. Here's the problems1.I captured and saved in stacks. The stacks saved as .sta files. According to the help files there is also an .its type file that they would save to. How do I save to this type of file.2. When I tried to open a stack with 6 images in it, it wouldn't. It used up all my memory (6.8 Gb for a file that claimed to be 4.5 Mb).Is there any way I can recover the individaul images from the stacks that can't be opened? How do I get the stacks to be saved as the proper type?Thanks,Linnea------------------------------Date: Sat, 7 Sep 1996 00:11:32 -0400From: SolamereTG@aol.comTo: it-list@sparky.uthscsa.eduSubject: support of direct to HD image recording  by IT?Message-ID: <960907001130_196159927@emout19.mail.aol.com>Hello to all:Does IT 1.23 support storing the digitized images directly to a hard drivepartition?

I have done this previously ona Macintosh using NIH-Image and a Hypercard program that converts a videofile to an image stack.  The image stack was then read into NIH-Image andpresto, the stack was averaged to give a single, noise-free image.  As I amusing a video grabber that is not compatible with Image Tool, I waswondering if anyone has come across a program that converts AVI files to animage stack that can be read by Image Tool for this purpose.HalldorHalldor Gudmundsson     |  Halldor.Gudmundsson@iti.isProject manager |Technological Institute of Iceland	tel: +354 - 587 - 7000	Keldnaholti, IS-112 Reykjavik	fax: +354 - 587 -  7409Iceland------------------------------Date:          Tue, 10 Sep 1996 11:57:00 +0000From: "Tony Collins" To: it-list@sparky.uthscsa.eduSubject: Even More Dt3155 problemsMessage-ID: I've finally got hold of all the relevent DT files and can now get IT to acquire images with my DT3155 frame grabber - kind of.

Up til now Ihave concentrated on acquistion of images. Now I wish to analyse some. Particularly is there a way for IT to view an image of discs(actually theshadow from spheres) where some of the discs overlap, and find out theaverage radii, but accurately taking into account the problem ofoverlapping objects so that reduced radii are not logged for thoseoverlapping discs. Merely iscounting objects with non circular outlines,is not appropriate because we may have many such overlapping discsIf a plug in is not available, does anyone have suggestions for1o: other softwar2: appropriate algorithms to write into a plug inor 3: intentions of writing a similar algorithm.------------------------------Date: Tue, 10 Sep 1996 14:28:22 +0100 (BST)From: Bryan Crosby To: IT-List HTHSCSA Subject: dt3157 (fwd)Message-ID: are there any plans to write and acquistion routine for IT to use dt3157all digital frame grabbers?yours sincerly 		Bryan Crosby------------------------------Date: Tue, 10 Sep 1996 18:16:16 +0100 (BST)From: Bryan Crosby To: IT-List HTHSCSA Subject: Brent DoveMessage-ID: What is Brent Doves direct address pleaseSincerely Bryan Crosby------------------------------Date: Tue, 10 Sep 1996 16:55:55 -0500From: kszaruba@mmm.com (Karen S. Zaruba)To: it-list@sparky.uthscsa.eduSubject: Re: Snappy -- Here's my $0.02Message-ID: <199609102155.AA094982555@dawn.mmm.com>Regarding Herek Clack's post I would also like to add a few "Snappy"comments and ask for advice.I also finally gave in a few months ago and bought a Snappy.  I think itcould be really cool for those working with VCR, camcorder and other typesof systems which use what I think are called "F-type" audio/video cables.However, in my lab we have CCD cameras which use BNC cables.  In order tomake Snappy work I had to get an adapter (only $5 but I wonder if thisaffects the performance.)The Snappy then works fairly well on one of our cameras, an 8 bit B/W, butthere are often interference lines running across the image.  On our colorvideo camera (just less than 8 bit) the only way to get an image is to wheelthe computer over right next to the camera and use its short 6' corddirectly into the Snappy.  Even then the image is extremely noisy.  Add anylonger BNC cords and the noise is too great for Snappy to recognize thesignal.  Also I had a demo of a 10-bit color camera in my lab and tried to"snap" an image but it came out with a "shadow" double effect (perhaps dueto the contortions of cables needed to hook to my computer on short notice?).Any advice on what I could do to improve the signal??  I am trying toacquire light microscopic images of histological sections.  My computers arenot located in the same rooms as the microscopes (no space).  Has anyonesuccessfully used a high resolution (10-bit or better) color camera withSnappy?  A second problem is with Windows NT.  Like a fool I chose NT over Windows 95when I found I couldn't run IT on Win 3.1.  Now I can't get NT drivers formany of my beloved peripherals (e.g. Snappy and Bernoulli drive).Supposedly NT runs much more smoothly than Win 95, but who cares if youcan't get drivers or installation setups for your software and hardware!(So far there is no love lost between me and NT).Any comment would be appreciated!
