I have a point shapefile "Negative_vel". With the command Analysis tools-Proximity-Buffer and selecting 50m as a linear unit and dissolve type ALL I created a new .shp "Negative_vel_buffer50m". But this new shapefile (with the buffer circular polygons) has no attribute table. I need an FID for each circular buffer polygon so that to check with Join Points to Layer how many points from the initial shapefile "Negative_vel" are within each buffer polygon. Because I need to keep only the polygon buffers with more than 3 points inside them. It is not of my interest to keep buffer polygons with just one point inside.
So, I need a buffer .shp dissolved with attribute table so later on to Join and count the points inside each polygon.
