| Clone & link (expert users) |
Github depository | Clone the Github depository to your computer and link folders from your clone to proper Igor locations. If you need help, let me know. NOTE: Github depository "master" version should be considered development version and while I try to submit to Github only working versions, the code is "beta" version only... |
| Older versions, no development anymore: | ||
| Igor 7.08 | Upgrade Igor Pro to higher version. Igor 7 is obsolete by now. | |
| Installer | GithubInstaller | Update to Igor Pro 7.08. Use Installer version 1.10 and install version 1.82 (February2020 release). Check Youtube channel for instructions. Higher versions than 1.82 are not tested on Igor 7.08 and may not work. |

Dropbox links if APS do not work: |
Due to changes to APS IT safety requirements, automatic download of the distribution file will not work. You need to download the IgorCode.zip file and install "Using local depository" method. For Igor 6.37; Installs/updates/uninstalls Nika, Irena, Indra, and 32 bit versions of xop, uses APS depository If you get "HDF5OpenFile" error, see here. |
