What exactly are you asking? You're TEM patterns, I assume, are saved. You can do whatever type of analysis you want with those files. You cannot successfully analyze any data if the data analysis software is a black box to you. You actually have to figure out how to analyze it yourself and exactly what each analysis program is doing and why before you can just take some numbers spit out by some software and expect to have something useful. You must be able to take the raw data and analyze it without commercial software before even thinking about doing further analysis.
Thank you for your suggestion. This is exactly the kind of input directed towards the analytical measurement.
For measuring the distance, you can use "imagej" software. the you have to calculate manually using the formula.
May be you could be interested in some tools of CrysTBox software (see the link below).
If you'd like to index a spot/disc diffraction pattern or HRTEM image, then diffractGUI can automatically index the zone axis and it also assigns plane indices to the diffraction/FFT spots. The possible inputs SAED, CBED, nanodiffraction or HRTEM.
If you are interested in a ring diffraction indexing, then ringGUI coud be the vote. It can assign plane indices to individual rings in the pattern.

You can try CSpot Software or E-Spot Software from CRYSTORIENT http://www.crystorient.com
how to download Crystallographic Tool Box (CrysTBox) software please send me link

you have to fill one application form here. then you will get the link. It is free of cost.
Sir /madam
Thank you for giving the software I have downloaded the CrystBox software but unfortunately, i am facing two problems
1) I could not download/ locate the CrysTBox.gt1 file
2) In the procedure dialog box ( Launch all, input item scale the input image and detect beam tabs are not appearing) how to make any changes such a way that they will appear.
please, suggest me to overcome this problem
Thank You
The iTEM Solution Diffraction extension makes it possible to automatically index, evaluate, measure and analyze diffraction patterns. As with all other extensions, the iTEM Diffraction is fully integrated with iTEM. The base-level version offers numerous functions for processing, analysis, visualization and archiving of images and other data as well as for automation and report generation. With its solution-oriented software extensions, iTEM's range of functions can be precisely expanded according to the user's needs.
Indexing diffraction patterns
Via iTEM Diffraction, diffraction patterns (SAED) of both single crystalline and polycrystalline samples can be indexed. After the crystal structure and lattice parameters have been defined, indexing is conducted via threshold detection (automatically) or via definition of the two g vectors (manually). Alongside the Miller indices, the zone axis is shown as the indexing result within the image overlay. The related lattice distances may be listed in a sheet automatically as needed. All data, including the image information is saved with the diffraction image.
Measuring within diffraction images
The Diffraction iTEM Solution offers easy analysis of diffraction patterns. Lattice plane distances are simple to measure as well as the angles between two different planes. The integrated snap function - which can be switched on and off - ensures the greatest possible precision. The snap function locates the brightest ambient point automatically and then uses this as a point of measurement.
Required Software
* iTEM Software (Manufactured by EMSIS previously Olympus)
Key Features
- Automatic analysis and indexing of digital electron diffraction pattern
- Determination of reciprocal units
- Direct readout of camera length
If you want to automatically identify the diffraction spots and measure their locations in the image, you could use software like MIPAR (www.MIPAR.us). It can even be set up to automatically identify the origin spot. You could then take the spreadsheet of location measurement to Excel or preferably MATLAB, using some simple trig to convert to indices. MIPAR also offers a free 30 day trial, with custom recipe support included if you need help with spot identification.
Hi, all software I found online was either unnecessarily complicated or too expensive (or both). So I decided to make my own:
https://www.odpin.com.
It's 100% non-commercialized, e.g. no ads, no registration, no collecting of user data. It's loosely based on something I wrote during my PhD to help me with the task of indexing diffraction patterns made with SAED.
What Odpin does is that it takes the crystal structure of your specimen and the geometry of your diffraction pattern as input and then calculates a list of possible combinations of (hkl) planes which fit to the geometry of your pattern with a deviation of less than 3%. You can then filter by selection rules, e.g. fcc, bcc and so on.
Maybe someone finds it useful :) Feedback welcome!
