Hello,
On inspection, it appears the Afzelia file is using semicolons to delimit, instead of the typical commas. Apologies that the log window message is not helpful in clarifying this issue, I'll see if I can adjust it.
However, it's an easy fix. Just check the box to define the delimit-separated and decimal values, and change the comma (,) to a semicolon (;). This will get the data to load.
If anyone else is having trouble loading user-specified data and receiving the error message " ! ERROR : Please input a file with columns "scientific_name", "longitude", "latitude"." always follow these steps:
1. Make sure the file is a .csv
2. Make sure the first three columns are properly named and in this order: scientific_name, longitude, latitude
3. Check your delimiter and decimal values. This box can be checked to specify the delimiter-separator and the decimal separators. They are typically a comma and a period, but this is not always the case.
